Hi again,
I've been away awhile and just got to respond to your posts. I hope that you are well today and got through the weekend okay.
Please listen to your body. The part of you that is driving the binging behavior may be your survivor instincts trying to keep you alive!! I know that your family is not supportive, but please find someone in your community who is! Have you looked online or in the phone book for an eating disorder clinic. I know you are afraid of getting "locked up" somewhere and that interfering with your future, but becoming even more sick from from starving and binging will interfere even more
You should also know that binging is a common accompanyment to anorexia. In fact, there are two kinds of anorexia. In one, the person starves themself without binging. In the second, the person also binges (and in some cases purges--through vomiting, diarea, etc.). Both kinds are extremely dangeraous to your health. In addition to the other site I gave you, here is the page from PC that looks pretty helpful:

Let me know if I can help in some other way.
