The short version
- Depression can look like sadness, but also numbness, irritability, exhaustion or loss of interest.
- Symptoms lasting most of the day, nearly every day, for two weeks or more deserve attention.
- Depression is common and treatable with therapy, medication or both.
Depression isn’t just a sad mood. For many people it feels more like heaviness, flatness or a slow draining of interest from everything that used to matter.
Common signs
Emotional
- Persistent sad, empty or “numb” mood

A rough patch or depression?
Clinicians look at how long symptoms last and how much they affect daily life. Major depression involves several symptoms, most of the day, nearly every day, for at least two weeks, causing real distress or difficulty functioning. Grief, burnout and medical conditions (like thyroid problems) can look similar, so a professional assessment helps.
Depression doesn’t always look the same
- It can be high-functioning: you keep working while feeling empty inside. See high-functioning depression.
- In some men, it may show up more as anger, risk-taking or substance use.
- It can be seasonal. See seasonal depression.
- After pregnancy, it may be perinatal depression.
Check in with yourself
The PHQ-9 is a widely used questionnaire that clinicians use to screen for depression. Our free depression screener uses it and keeps your answers on your device. It’s a starting point for a conversation, not a diagnosis.
Treatment works
Therapy (such as CBT, behavioral activation or interpersonal therapy), medication, or a combination help most people. Lifestyle supports like movement, sleep and connection make a real difference alongside treatment.

Can depression go away on its own?
Sometimes mild episodes improve, but depression often returns or lingers without support. Treatment shortens episodes and lowers relapse risk.
Is depression a sign of weakness?
No. Depression is a common health condition influenced by biology, life events and stress. It is not a character flaw.
