I was sorry to read your reply about not having anyone else to talk this over with, so here's my two cents:

You said last week that you actually lost some weight but were still unhappy. So maybe the problem you are struggling with isn't your weight? And maybe this realization is what lead to the panic that you wrote about?

In reading up a bit on ED's in an effort to help my daughter, I've found more than a few experts who say that the eating behavior is actually not the true problem in many cases. Their claim is that the ED behavior is a reaction to the seeming inability to solve or control the true underlying problem.

Could this be what going on for you? This is why I'm thinking you need to consult with someone with the proper credentials in order to help you get to the bottom of all of this.

Although it's tough, but as a parent I would be open to talk to my kids about absolutely anything--and I wouldn't judge them or think less of them one bit for coming to me with whatever was bothering them. I would be happy to help them in whatever way I could--either helping them deal with their problems directly or in helping them get any outside help that may be needed.

Good luck and understand that you are not alone in this--it's actually alot more prevalent than I ever thought. Take your time, settle down, don't panic, you'll get there. You've already taken the first steps.
