You will recover yourself. You've gotten some good advice. Do your best to follow some
of the suggestions.
As from my own experience I'll say I have had that feeling many times . I needed a lot of
help. Professional help. Sometimes even a hospital if necessary. Talking about it to whoever would listen , even to those who wouldn't. Trying all different kinds of meds.
I could not WILL my depression away like everybody else thought I should be able to.
Now I'm not just talking about the occasional blues that last a short time and people can get out of.

My depression doesn't end. I just try and deal with it. And keep telling myself that
someday it will all end.
