i'm struggling. Why won't this depression go away for good?

[YesBut]

oh dear How long have you had it? Are you on medication? Anything in particular that triggers it?

As someone who has come out the other side of severe depression, I can say that it is possible to get better.

Hang in there.

on and off for year anda half, better than it ewas, but sometimes it just hits me/ Am off medication and about to be discharged from mental health team
