I echo what Lizzyjb says and add a piece. Even if you do not enjoy something that you used to enjoy because of depression, try with all your might to do it anyway, whatever it is. A cup of jo by yourself at a coffee shop..I dunno, whatever. A comedy...even if you don't laugh. Your depressed brain isn't enjoying it, but your brain chemistry is getting a message. Putting one painful step in front of the other.

I think the idea of "Radical Acceptance" is great...as Skeetzy mentioned, to a degree. Let yourself feel like s...t, accept it try to not pressure yourself into feeling different...you may just discover the time will come, sooner rather than later, when you feel well enough to start "faking it 'til you make it." "What you resist perhaps," it is hard, but true and your depressed brain will fight that.

If you aren't functioning under the philosophy if acceptance for a couple weeks, IMO, time for in person mental health crisis intervention. There are people who care, us, more importantly in person help.

For what that's worth.
