You know, sometimes it really is easier to post about stuff on the web than it is to talk to someone in person. So post away, we will listen.
I'm glad you're seeing someone, and trying to learn how to cope with things and take better care of yourself. You really deserve that.
For what it's worth, I know how scary it is to realize that you have to give up the crutches you have been depending on, but it's worth going through the crap to get to a point where you can learn better ways of coping.
I planned to say more - I wanted to post something deep and profound that would leave you feeling hopeful and motivated, but I'm coming up short. Sorry. I hope you know I"ll be thinking of you. Hell, I get having no self-worth and hating your body and all that... I really hope you can get past that.
