I was taking (and still am) Topamax for Bipolar, which helped me to lose a great deal of weight in the beginning. Well, my therapist told my pdoc about my anorexia, and my pdoc, being an eating disorder specialist as well, contributed my eating disorder to the fact that I was on Topamax. She threatened to take Topamax away from me. That was my wonder drug and I feared I would gain all the weight back. I told her it worked for my moods and I couldn't bear to go off it. We agreed upon a healthy weight, which was thin enough for me, anything to stay on Topamax. I just did not want that drug taken away at all. I think that is what helped me.
Also, I started Prozac for depression and that is supposed to help with eating disorders too. It kinda gave me a "who cares" attitude.
I still sometimes wish I was back in that place where I was last year, thin as bones. I still don't eat healthy. I eat junk and skip meals to make up for it. I still fit in some of the same clothes, but fat hangs out. Gross!

It sounds like you're really wanting help, keep posting and let us know how you are doing.
Take care,
