Depression support, and what actually helps versus what sounds helpful
Depression support means different things depending on severity, and conflating all of them into one piece of generic advice ("just get outside more") is part of why depression support content so often feels useless to the people who actually need it. Some of what helps is genuinely self-directed. Some of it requires a clinician. Knowing which is which matters.
This page is about what research actually supports, not a list of good intentions.
The treatments with real evidence behind them
Research from the National Institute of Mental Health (NIMH) has specifically identified cognitive behavioral therapy (CBT) and interpersonal therapy (IPT) as psychotherapies that reliably help relieve depression. CBT works by directly addressing the negative thinking and behavior patterns that depression tends to produce and reinforce, not just by providing a space to talk.
Medication, talk therapy including telehealth and online formats, and in some cases brain stimulation therapy are the treatments NIMH research is actively working to refine and personalize, on the basis that different treatments work better for different people, not that one approach is universally correct.
Self-management is a real, evidenced adjunct, not a stand-in for treatment
Evidence-based self-management strategies, tailored to a person's own preferences and values, are a documented, useful complement to traditional treatment, not a substitute for it. This distinction matters because self-help content aimed at depression often implies it can replace treatment when the actual research frames it as something that works alongside it.
It is also worth being direct about what does not work as a stand-alone approach: relying solely on complementary or alternative methods, without psychotherapy or medication where those are indicated, is not sufficient treatment for depression on its own, per the same body of research.

The two-week line is a real, research-backed threshold
NIMH guidance is specific here: severe or distressing symptoms lasting two weeks or more is the point at which professional help, starting with a primary care provider who can refer to a psychologist, psychiatrist, or clinical social worker, is the appropriate next step, not an overreaction.
This threshold exists precisely because low mood that lifts within days is different, clinically, from a sustained depressive episode, and treating the two the same way, either by minimizing a real episode or over-medicalizing a passing low mood, does not serve either situation well.
Under two weeks, situational
A rough patch tied to a specific event usually eases with time, support, and ordinary self-care.
Two weeks or more, persistent
This is NIMH's own threshold for when to involve a professional, not an arbitrary cutoff.
Self-management, alongside treatment
Genuinely useful once real treatment is in place or being pursued, not instead of it.
Try this
If it has been close to two weeks of persistent low mood, loss of interest, or hopelessness, that itself is the signal worth acting on, not a threshold to wait past to see if it gets worse first.
Where a companion fits, and where it plainly does not
A companion can be a genuine part of the self-management side of this picture: a place to name what a day actually felt like, notice a pattern across weeks, and rehearse how to bring this up with a doctor. It is not equipped to be the treatment itself, and Health and Kind says so directly rather than blurring that line, because the research is clear that self-management works alongside real treatment, not in place of it.
Common questions
What actually helps with depression, according to research?
NIMH research points specifically to cognitive behavioral therapy (CBT) and interpersonal therapy (IPT) as psychotherapies with reliable evidence, alongside medication and, in some cases, brain stimulation therapy, personalized to the individual.
Can self-care alone treat depression?
Evidence-based self-management is a documented, useful adjunct to treatment, not a replacement for it. Relying solely on complementary or alternative methods without therapy or medication where indicated is not sufficient treatment on its own.
When should depression be taken to a doctor?
NIMH guidance points to two weeks or more of severe or distressing symptoms as the threshold for seeking professional help, starting with a primary care provider who can refer to a specialist.
Is it normal to feel low for a few days without it being depression?
Yes. Situational low mood tied to a specific event that eases within days is different from a persistent depressive episode. The two-week threshold exists specifically to distinguish between them.
Can an AI companion help with depression?
It can be a genuine part of the self-management side — naming patterns, tracking how days actually feel, and rehearsing a conversation with a doctor — but it is not equipped to be the treatment itself, and should not be treated as a substitute for real care.
