What Is Depression?
Depression can affect your mood, interest in life, sleep, energy, and ability to get through the day. Major depressive disorder involves a depressed mood or loss of interest, along with other symptoms that persist and interfere with daily life. It is a health condition, and treatment can help.[1]
You may notice sadness, irritability, or feeling emotionally empty. You might stop enjoying a familiar activity, struggle to make decisions, or find that ordinary responsibilities take much more effort. Experiences vary. You do not need to look visibly sad for your symptoms to deserve attention.[1]
- Depression is common. The World Health Organization estimates that about 322 million people worldwide experienced depression in 2023.[2] That estimate includes people of different ages and is not a count of U.S. adults.[2]
- Either core symptom can be present. Persistent low mood or loss of interest, with other symptoms, can be part of depression. A clinician considers the full pattern and its effect on your life.[1]
- There are several treatment options. Psychotherapy, medication, or a combination may help. Your symptoms, health, preferences, and previous treatment shape the choice.[1]
- An unsuccessful treatment is a reason to review the plan. A clinician can check the diagnosis, side effects, treatment delivery, and other problems before discussing another approach.[3]
- You can ask for help before a crisis. A primary care professional or mental health clinician can assess persistent symptoms. You do not have to wait two weeks if you are unsafe or struggling to function.[1]
Depression Symptoms and Daily Life
Depression affects more than feelings. Changes in thinking, physical energy, sleep, appetite, and behavior can occur together. Loss of interest or pleasure is called anhedonia. For example, someone may still attend a family gathering but feel little enjoyment or connection.[1]
The following symptom areas can help you describe what has changed. They are a conversation guide, not a self-diagnosis. Symptoms also occur with other conditions, and not everyone with depression experiences every one.[1][4]
| Symptom area | What you might notice |
|---|---|
| Mood | Feeling persistently sad, empty, hopeless, or irritable. |
| Interest | Little interest or pleasure in activities you usually enjoy. |
| Appetite and weight | Eating noticeably more or less, or an unplanned weight change. |
| Sleep | Difficulty sleeping, waking early, or sleeping much more than usual. |
| Energy | Fatigue or a lack of energy that affects ordinary tasks. |
| Movement | Noticeable slowing of movement or speech, or unusual restlessness. |
| Self-worth | Feeling worthless or excessively guilty. |
| Thinking | Trouble concentrating, remembering, or making decisions. |
| Safety | Thoughts of death or suicide. Seek support promptly rather than waiting to complete a checklist. |
These symptom areas are described by NIMH and in the Merck Manual’s clinical reference. For more examples, see depression symptoms.[1][4]
When Depression Symptoms Need Urgent Help
If you are thinking about suicide or need immediate emotional support, call 988, text 988, or use 988 Lifeline chat. This U.S. service is free and available 24/7. Call 911 for immediate danger or a life-threatening emergency.[5][1]
Depression, Sadness, and Grief
Sadness after a setback and grief after a loss are not automatically depressive disorders. Grief can include waves of painful feelings alongside positive memories. Depression more often involves a sustained change in mood or interest, with broader effects on functioning. These patterns can overlap, and grief and depression can occur together.[4]
Being able to laugh, work, or enjoy a moment does not settle the diagnosis. Tell a clinician about the duration, intensity, and effect of your symptoms rather than trying to prove that you feel bad all the time. Loss also deserves support even when a depressive disorder is not diagnosed.[3][4]
How Depression Is Diagnosed
A depression diagnosis requires an assessment, not just a questionnaire score. Clinicians ask about symptoms, duration, previous episodes, and changes in relationships, work, school, or self-care. For a major depressive episode, depressed mood or loss of interest must be present most of the day, nearly every day, for at least two weeks.[1][4][3]
A major depressive episode involves at least five of nine symptom areas during the same two-week period, including depressed mood or loss of interest. The symptoms must represent a change and cause significant distress or impaired functioning. Clinicians also consider other explanations and whether the episode occurs within bipolar disorder.[4]
Tell your clinician about periods of unusually elevated or irritable mood, increased activity, or needing much less sleep. A history of mania or hypomania can change the diagnosis and treatment. Physical illnesses, medications, and alcohol or other substances can also cause or contribute to depression-like symptoms.[1][3]
What Screening Can and Cannot Tell You
Tools such as the PHQ-2 and PHQ-9 ask about recent symptoms and can identify a need for further assessment. A positive result does not establish depression, its cause, or the right treatment. Screening is useful when it leads to evaluation and access to appropriate care.[6]
U.S. preventive guidance recommends depression screening for adults without recognized symptoms, including pregnant and postpartum adults. It does not establish a recommendation for routine suicide-risk screening in that same population. That distinction does not mean ignoring suicidal thoughts in someone who is depressed. Clinicians should assess those concerns directly.[6][3]
Before an appointment, note when symptoms began, what daily tasks have changed, medications and supplements you take, substance use, and previous treatments. Include your biggest concern, such as sleep, caring for children, or thoughts of self-harm. This gives the clinician a useful starting point.[1][3]
Types and Patterns of Depression
Depression has several diagnoses, patterns, and features that can change the care you need. The terms below are not interchangeable. A clinician considers the course of your symptoms and your wider health history.[1][3]
| Term | What it describes | Why it matters |
|---|---|---|
| Major depressive disorder | Depressive episodes that interfere with daily life. | An episode may occur once or recur. History and current severity guide treatment.[1] |
| Persistent depressive disorder | Depressive symptoms that continue for a long period, usually at least two years in adults. | Longstanding symptoms still warrant assessment and treatment. They should not be dismissed as simply your personality.[1] |
| Seasonal pattern | Depressive episodes linked to particular seasons, most often winter but sometimes summer. | Treatment and its timing depend on the pattern. Light therapy is an option for winter-pattern symptoms, with medical precautions.[7] |
| Perinatal depression | Depression during pregnancy or after childbirth. | A clinician should consider both the parent’s needs and pregnancy or breastfeeding when discussing treatment.[1][6] |
| Psychotic features | Depression with hallucinations or delusions. | This needs prompt specialist assessment and coordinated treatment. Medication combinations or ECT may be considered.[3] |
Clinicians may also describe features such as melancholic or atypical symptoms. These describe aspects of an episode rather than a diagnosis you can establish from a label. Different types of depression can involve distinct patterns and care needs.[4]
Bipolar depression belongs to bipolar disorder. It can resemble major depression during a low episode, but a history of mania or hypomania changes the treatment considerations. Tell your clinician about both low periods and unusually energized periods.[1][3]
What Causes Depression
Depression develops through a combination of biological, psychological, and environmental factors. Family history, stressful experiences, physical illness, and social circumstances can contribute. Having a risk factor does not establish why one particular person became depressed.[1][2]
Brain Chemistry, Stress, and Life Experience
The biology is more complex than a simple shortage of serotonin. Researchers study several interacting systems, including brain signaling, the body’s stress response, inflammation, and neuroplasticity, which is the brain’s ability to adapt its connections. A 2026 review describes these as overlapping research pathways, not a single proven explanation for every person’s depression.[8]
These findings do not provide a routine test that identifies your individual cause or selects the perfect medication. Much of the research describes differences between groups, and proposed biological subtypes still need validation. Clinical assessment and your response to treatment remain important.[8]
Depression can run in families, but it is not inevitable when a relative has it. Loss, trauma, abuse, unemployment, isolation, and other stresses can contribute to risk. Depression can also make those difficulties harder to manage. Treatment may need to address both symptoms and practical pressures.[1][2][3]
For a fuller discussion of risk factors and what they do and do not explain, see causes of depression.
Depression Treatment Options
Effective treatments include psychotherapy, medication, and, for some people, specialist treatments. The choice depends on symptoms, severity, previous treatment, other health conditions, and your preferences. Therapy is often an initial option for milder depression. Medication may be part of the initial plan for moderate or severe depression.[1]
Agree on what improvement would mean for you, such as getting through the workday, reconnecting with people, or sleeping more regularly. Ask when progress and side effects will be reviewed and whom to contact if you feel worse. A treatment plan should include follow-up, not just a prescription or referral.[3]
How Talk Therapy Helps
Structured psychotherapy helps you work on patterns that contribute to symptoms or make life harder while you are depressed. Sessions can be individual or in a group, and some therapies can be delivered online. The provider’s training and the treatment approach matter alongside the delivery format.[1][9]
| Approach | What you work on | What to ask |
|---|---|---|
| Cognitive behavioral therapy | Recognizing unhelpful thinking and behavior patterns and practicing different responses.[1] | How will we connect sessions to situations I face during the week? |
| Behavioral activation | Identifying links between activity and mood, reducing avoidance, and gradually rebuilding meaningful activities.[3] | How will we choose manageable steps when my energy is very low? |
| Interpersonal therapy | Working on relationships, communication, life changes, and support that affect mood.[1] | Which relationship or life changes would we focus on? |
Psychology Tools' behavioral activation guide recommends breaking activities into smaller steps and choosing activities connected to what matters to you. That gives the idea of “doing more” a specific starting point when your energy is low.[21]
For example, if keeping in touch with a friend matters to you, a first step might be writing one short message rather than planning an entire outing. Discuss the size of the step with your therapist and adjust it to what you can manage.
Therapy avoids medication side effects, but it still involves effort, time, and sometimes difficult conversations. Tell the therapist if the approach, pace, or relationship is not helping. You can discuss adjustments or another approach. Combining therapy with medication is an option, not proof that either treatment has failed.[3][9]
Antidepressants and Follow-Up
Antidepressants affect chemicals involved in mood and stress. Common groups include selective serotonin reuptake inhibitors, or SSRIs, and serotonin-norepinephrine reuptake inhibitors, or SNRIs. Medication choice should account for previous response, other medicines, health conditions, and side effects that matter to you.[10][3]
NIMH describes antidepressants as usually taking four to eight weeks to work. Sleep, appetite, or concentration may improve before mood. That is not a reason to wait silently through worsening symptoms or intolerable side effects. Agree on an earlier check-in and contact the prescriber when concerns arise.[1][3]
Possible side effects include nausea, sleep changes, weight changes, and sexual difficulties. Some ease, but others can persist. Children, teenagers, and young adults under 25 can have an increased risk of suicidal thoughts or behavior when taking antidepressants. People of all ages need monitoring, especially after starting treatment or changing a dose.[10][1][3]
Do not stop or reduce an antidepressant on your own. Withdrawal can follow an abrupt stop, missed doses, or dose reductions. Symptoms can include dizziness, nausea, sleep problems, anxiety, and unusual electric-shock sensations. Severity and duration vary, and some people have substantial or prolonged difficulties.[3]
If you want to stop, work with the prescriber on an individualized, gradual reduction and follow-up plan. Tapering can take weeks, months, or longer, and the pace may need to change according to symptoms. Withdrawal and returning depression require assessment rather than assuming that either explanation fits every symptom.[3][11]
Ask your clinician how antidepressants fit with other depression treatment options.[3]
When Treatment Is Not Helping Enough
A limited response is a reason to review the plan with your clinician. Discuss how treatment was delivered, missed sessions or doses, side effects, ongoing stress, substance use, and other medical or mental health conditions. Sometimes the diagnosis or treatment approach needs to be reconsidered.[3]
The STAR*D study illustrates why follow-up matters. In its first medication step, about one third of participants reached remission with citalopram.[12] Some benefited from later steps, but later-step remission rates were lower and dropout increased. Those study results do not predict your individual chances or mean that persistence guarantees recovery.[12]
Options may include adjusting a medication, switching treatment, adding psychotherapy, or specialist consultation. Adding another medication can introduce new risks and monitoring needs. For example, lithium or an antipsychotic requires a careful discussion and appropriate physical-health monitoring.[3]
ECT, TMS, and Esketamine
Electroconvulsive therapy, or ECT, uses an electrical stimulus under anesthesia to produce a controlled seizure. It may be considered for severe depression after other treatment has been unsuccessful, or earlier when a rapid response is needed because the illness is life-threatening. Memory problems, confusion, and anesthesia risks need discussion.[3][13]
Transcranial magnetic stimulation, or TMS, uses magnetic pulses to stimulate targeted brain areas. It generally does not require anesthesia. Headache and scalp discomfort can occur, and seizures are a rare risk. Eligibility, treatment schedules, and follow-up depend on the device, protocol, and clinical assessment.[13]
Esketamine nasal spray, sold as Spravato, is FDA-approved for treatment-resistant depression in adults, either alone or with an oral antidepressant. It is administered under professional supervision with at least two hours of monitoring through a restricted safety program. Risks include sedation, dissociation, breathing problems, increased blood pressure, and misuse.[14]
Spravato also has a separate indication for depressive symptoms in adults with major depressive disorder and acute suicidal thoughts or behavior, used with an oral antidepressant. It has not been shown to prevent suicide and does not remove the need for hospitalization when clinically necessary.[14]
Other ketamine formulations are not interchangeable with Spravato. Ask the treating clinician about the specific product, approval status, monitoring, evidence, and alternatives. Do not delay urgent help while waiting for a specialist treatment appointment.[15][14]
Depression and Substance Use
Assessment should consider both mood symptoms and alcohol or drug use. The conditions can occur together, and substances can cause or worsen mental health symptoms. A clinician needs to understand when symptoms began and how they relate to substance use, withdrawal, and periods without use.[16][17]
Ask whether your providers will coordinate care and address both concerns. The order and setting of treatment depend on your needs, including withdrawal risk, medical stability, and immediate safety. Needing urgent substance-use care should not mean that suicidal thoughts or other serious mental health symptoms are ignored.[16][17]
Alcohol withdrawal can be dangerous. If you drink heavily and regularly, ask a health professional about stopping safely. Abruptly stopping benzodiazepines can also cause serious withdrawal. Seek emergency care for seizures, severe confusion, or other life-threatening symptoms.[18][19]
Depression Across Different Lives
Age, pregnancy, physical health, and access to care can affect assessment and treatment. A useful plan accounts for your circumstances rather than assuming that everyone experiences depression the same way.[1][3]
During pregnancy or after childbirth, tell your maternity or primary care clinician about mood changes, anxiety, loss of interest, or difficulty functioning. Treatment decisions should consider the risks of untreated illness alongside treatment benefits and risks. See postpartum depression for more information.[1][6]
Children and teenagers may show irritability, school difficulties, or withdrawal rather than describing sadness. They need an age-appropriate assessment and treatment plan. Medication decisions and monitoring should involve a clinician experienced in treating young people.[1]
Older adults may describe loss of emotion, physical complaints, or memory and thinking difficulties. Other illnesses and medications may contribute, so assessment matters. These changes should not automatically be dismissed as normal aging.[1]
Depression can occur in people of any gender or background. Some people find it easier to discuss fatigue, sleep, anger, or drinking than emotional pain. Cultural expectations, stigma, cost, language, disability, and local service availability can affect how people seek and receive help.[1][3][2]
Finding Depression Therapy Near You or Online
Start with the type of help you need, then compare practical fit. A primary care professional can assess symptoms and medical contributors. A licensed therapist can provide psychotherapy. A prescribing clinician is needed when medication is part of the plan. More complex or severe symptoms may need specialist or urgent care.[1][3]
When searching for depression therapy near you, look beyond distance alone. Ask about experience treating depression, the therapy offered, costs, insurance, accessibility, and appointment availability. If several providers are involved, ask who will coordinate the plan and review progress.[9][3]
Some primary care practices offer collaborative care. In this model, a care manager helps connect you, your primary care clinician, and mental health specialists. Ask whether that type of coordinated support is available if arranging care across separate services is difficult.[6]
- Treatment fit. What approach do you use for depression, and how will we know whether it is helping?
- Related needs. Can you coordinate care for substance use, physical illness, pregnancy, or another mental health condition?
- Cost. Are you in my insurance network, what might I pay, and are reduced-fee options available?
- Access. What appointments are available, and can the service meet my language, disability, or transportation needs?
- Follow-up. Who should I contact between visits, and what happens if symptoms become urgent?
Choosing Online Therapy
Online therapy can be an option for depression, but services differ. Confirm that the clinician is licensed or otherwise authorized to treat you where you will be during appointments. Ask about the treatment format, privacy, technology requirements, and arrangements if you need in-person or urgent care.[1][20]
Video sessions, messaging, and self-guided programs provide different levels of contact. Check what a subscription includes, whether medication management is offered, and how your therapist communicates with other clinicians. Do not assume that a platform’s depression listing establishes the right level of care for your situation.[20][9]
If cost or availability is a barrier, ask a primary care practice, community mental health service, or insurer about options. SAMHSA’s FindTreatment.gov can help you locate services. Explore treatment and support options when considering care.[1]
Living With Depression and Getting Support
Improvement can involve both fewer symptoms and a return to activities that matter to you. Response means symptoms have improved, while remission means symptoms have largely subsided. Neither is a guarantee that depression will never return. Review progress with your clinician and discuss what continued care could help maintain it.[12][3]
Relapse prevention may include continuing medication, further therapy, or both, depending on your history and preferences. It can also include recognizing early warning signs, identifying predictable stresses, and making a plan for getting help if symptoms return. Do not stop medication simply because you feel better.[3]
For people at higher risk of relapse, options can include relapse-focused CBT or mindfulness-based cognitive therapy, known as MBCT. These are structured therapies with a specific prevention goal, not simply advice to meditate. Discuss whether one fits your needs and how it would work alongside other continued care.[3]
Daily habits can support treatment. Start with manageable steps such as regular meals, a consistent sleep routine, some movement, and contact with someone you trust. These steps are support, not a test of willpower or a substitute for needed treatment.[1]
If you are supporting someone, listen without demanding that they feel better. Offer specific help, such as arranging transport, sitting with them while they make an appointment, or checking in at an agreed time. Encourage care and take statements about suicide seriously.[1]
Depression is treatable, even when finding a helpful plan takes time. Your next step can be describing what has changed and asking for an assessment. Mention anxiety, substance use, or other mental health concerns when arranging care so they can be considered together.[1][3]

Frequently Asked Questions About Depression
Is Depression Curable?
Depression can improve with treatment, and some people reach remission, meaning symptoms have largely subsided. Depression can also return or remain difficult to treat. The goal is to reduce symptoms, restore functioning, and develop a plan for staying well. No treatment can promise a permanent cure for everyone.[1][3]
What Are the Main Symptoms of Depression?
The core symptoms are persistent low mood or loss of interest or pleasure. Other symptoms can involve sleep, appetite, energy, concentration, movement, self-worth, and thoughts of death. A clinician considers the combination, duration, impact, and possible alternative explanations. You do not need every symptom to ask for help.[1][3]
What Is the Difference Between Depression and Sadness?
Sadness is an emotion that can follow difficult experiences. Depression involves a persistent pattern of mood or interest changes and other symptoms that affect daily life. Grief can include both painful feelings and positive memories, and it can occur alongside depression. A clinician can help assess the difference when symptoms persist or functioning changes.[1][4]
Are Antidepressants Addictive?
Antidepressants are not generally associated with the craving and compulsive use that characterize addiction, but your body can adapt to them. Reducing or stopping them can cause withdrawal, which can be severe or prolonged for some people. Discuss an individualized taper and follow-up with your prescriber rather than stopping abruptly.[3][11]
What Is the Best Treatment for Depression?
There is no single best option for everyone. Psychotherapy, antidepressants, or both may be appropriate depending on severity, your health, preferences, and previous treatment. A plan should include monitoring and a review if it is not helping. Severe or complex depression may require specialist care.[1][3]
Can Depression Go Away on Its Own?
Can Online Therapy Help With Depression?
Psychotherapy delivered online can help with depression. Check the clinician’s qualifications, approach, authorization to treat you where you are, and arrangements for urgent or in-person care. Online services differ, and therapy, messaging support, and medication management are not necessarily included in the same service.[1][20]
How Do I Find Affordable Depression Therapy Near Me?
Ask your insurer, primary care practice, or a community mental health service about local options. When contacting a provider, ask about insurance, expected costs, reduced fees, and appointment availability. SAMHSA’s FindTreatment.gov is another starting point. Confirm the service offers the type of depression care you need.[1][9]
