I do OK, for the most part. I have a lot of the same problems you do, particularly financially and health wise right now, but the one is a result of just choosing a low-paying field and the other -- eh, let's not go there.

I went through multiple kinds of abuse at the hands of both parents, but I have a graduate degree (completed while severely depressed), decent friendships (though I moved out of the town where most of my friends are, I'm still in close contact), a job in my field, etc.

I have days where it all bites me in the butt -- I don't know if that ever goes away. But I've learned to cope with it, more or less, and get on with my life.

I hope that helps.
