I can relate to you so much! Hopefully sharing your struggles will help. I'm new to ED recovery myself. I also remember my first binge... I was the same age you were, actually, about 7! I remember perching on the counter, eating an entire box of wheat thins and I felt so sick afterwards. I also remember around that time eating a whole giant tube of tootsie rolls, the kind of tube that is about 3 feet long. To this day I hate tootsie rolls because I made myself so ill with them.
I must have had a freakish metabolism because I did not struggle with weight issues until my late 20s (I'm 37 now). I am having a major battle with it now though.
Glad we are here to support each other!
