Hello withoutaplan: I'm sorry you are struggling with this.

I'm not a mental health professional. So I certainly cannot diagnose you. But from what you wrote, I would say it's likely the difficulty you are having is as a result of depression. Depression, along with anxiety, is something I struggled with over the years & I know I spent many years "not doing" the same sorts of things you're not doing.
I do think it would be worthwhile for you to look into some individual therapy as a way of beginning to sort through the difficult experiences you've had & how they may be affecting you now. It can sometimes take a while to find a therapist you feel comfortable with. But if you can find one, you may find talking your experiences through with that person most helpful. At least it would certainly be worth a try.
I see this is your first post here on PC. So...

to PsychCentral… from the Skeezyks!
