Eating disorder?

I was nearly bulimic a year ago, never actually got to the throwing up though. Anyway thought I had gotten over it but this last term of school has been so stressful, and I’m afraid I am starting to show symptoms of anorexia. I ALWAYS feel guilty after eating, I have tried to skip as many meals as possible, I feel huge even though I am perfectly normal, or so the scales say, and I feel as if I have to exercise all the time (even though I don’t). I don’t like to think about how many plans I have thought up to evade food, or to go on diets. I like it when I feel hungry, it makes me feel in control and thin. I don’t want to become anorexic, I am really scared, what do you think I should do? Telling my parents is not an option.
