Depression is chronic dysregulation of mood, motivation, and somatic function.
Major depressive disorder or persistent depressive disorder. Use selective serotonin reuptake inhibitor or serotonin-norepinephrine reuptake inhibitor plus psychotherapy first-line. Use electroconvulsive therapy, ketamine, transcranial magnetic stimulation for refractory. Screen for suicide.
So why does any of that happen in the first place?
Why this happens.
Here is how it usually shows up in real life.
What you might feel or notice.
Doctors use the Patient Health Questionnaire-9 to check for depression. They ask about suicide at every visit. Depression often comes with anxiety, drugs, or other health problems. Each of these findings ties back to you feel sad a lot — they are not a random checklist. At the bedside, your job is to spot the pattern first, then check the broken part.
When this lands in front of a clinician, this is what they are doing.
How clinicians treat it.
For mild depression, try talking therapy first. For moderate or severe, use a selective serotonin reuptake inhibitor or serotonin-norepinephrine reuptake inhibitor plus therapy. Wait 4-6 weeks to see if it works. If not, add medicine or switch it. For hard cases, try lithium, antipsychotic medicine, ketamine or esketamine, brain stimulation, or electroconvulsive therapy. Fix sleep and exercise. Stop using drugs. Make a safety plan. Postpartum depression needs special treatments. Each medicine on this list does a body job.
Common medications.
Examples your care team may use for depression. This is general education — your own plan, doses, and cautions come from your prescriber and pharmacist.

Beyond the clinic, the day-to-day choices that move the needle most:
What helps day to day.
- Sleep, food, and movement matter more than any single appointment — protect them.
- Therapy works best alongside medicine; ask about cognitive-behavioral therapy.
- Cut back caffeine and alcohol while symptoms are active — both make anxiety and mood worse.
- Tell one person you trust what is going on; isolation makes everything harder.
And underneath all of that, the life context that no medicine can fix on its own.
How well anyone does with this condition is shaped by life circumstances — stable housing, transportation to appointments, affordable medicines, food security, support from people nearby, and safe time off work or school. Stable housing, freedom from violence, and a trusted person nearby change outcomes more than any single medicine. Ask about low-cost or sliding-scale therapy and community peer-support groups.
But first — the moments that mean stop reading and get help.
When to get help right away.
!Sudden severe symptoms that are new or rapidly worsening — call 911.
!Anything that feels wrong and is getting worse hour by hour.
!When in doubt, call your care team or go to the emergency room.
When you do see your care team, these are worth asking out loud.
Questions worth asking.
Zooming out, here is what a life with this usually looks like.
Zooming out.
Recovery and stability are usually not linear — better weeks and harder weeks come and go. What helps most is the steady stuff: sleep, daily movement, therapy if it is available, medicines taken on time, and at least one trusted person you can call. Many people do well long-term and live full lives; what they have in common is naming the condition without shame and treating it like any other chronic health thing.
You do not have to figure this out alone.
