All I can say is that you need to get professional help. Period. You stopped seeing that counselor after only one visit? That's not nearly enough, and if your mother thinks that you can be "fixed" in an hour, it might help if you could get some information about it to her. A good book is Surviving an Eating Disorder. Maybe see if you can get it at the library, and offer it to your mother?

Whatever you do, though, get help now. Not later, but now. I go to a support group for people with eating disorders, and you know what? It never gets better on its own. It only gets worse. And the longer you wait before getting help, the worse it gets.

Get help now. And good luck.
