How can i stop eating chocolate & junk! and i need healthy advice?

You need professional help since you've been diagnosed, I'm uming, with anorexia nervosa. Your PCP or counselor should get you started on a nutritional program and therapy for your eating habits. And since you have issues like this, start researching information for yourself online or in the library. I'm happy you understand and accept what is going on within yourself. You should be very successful at getting yourself to a better place in life concerning this problem. Stay strong. You can beat this.
