Hi :) My name is Ali, I'm 16 years old, 5'6" and 120lbs. I've lost about 16 pounds since... November. But the problem with me is I'm bulimic. No matter how hard I try, I can't seem to keep food in my stomach. If I try to, I have a nervous break down and do whatever I can to get rid of the food and burn off the calories consumed. My goal (extreme, yes) is to be 75 pounds but I know I cant get down to that. I need someone to help me get better and get healthy. Please help!!
