Last summer was really rough for me for a number of personal reasons. I've always been pretty thin so I never thought I would be the victim of anorexia/bulimia. But for some reason I've developed this intense fear of gaining weight. It started off as simply eating healthier. I took out fast foods and soda from my diet, and it was all good. Over time though, it's progressed into being obsessed with counting calories and feeling extreme guilt after eating anything. I've limited myself to eating up to 1100 calories a day (although there are some days that I only eat about 5-600). If I go above that, I feel terrible about myself. I weigh myself daily and I've went from 103 pounds to 95. (I'm 5'6). I measure my waist and hips constantly. I still feel in control right now, but I'm scared I'm going to loose that control and I don't know what to do. 
My parents have noticed I've been eating less and less. And I've told them that I feel guilty for eating but I don't know if they take me very seriously.
