Hello and welcome.
I wish I had tons of good advice to give you, it sounds like a few here already are.
The change that comes, losing friends and relatives when you admit your skepticism or lack of belief is tough, especially if you already suffer with mental health issues. I sympathize, though I have not had the severity you describe, I also suffer from mental health issues (depression and severe anxiety). It makes it very hard to break free from the comfort of the people and places you know, even when you realize they are false and perhaps even bad for you.
I hope you find it in yourself to act on your own beliefs, or lack-there-of, and come to realize someday that you don't need the tainted candy (or sex, or love, or whatever) that comes at the high price of emotional blackmail.
My best wishes.
Hanging out with like minded people on these forums has helped me through the depressing aspects of my own deconversion, and I hope we can be some support for you too!
