Every time I eat something I get sick. I feel like I have to throw up or my stomach hurts extremely bad. It doesn't matter about the size of the portion because I'll get sick if it's big or small. It's at the point where I'm losing weight. I'm 5'2" and 15 years old. I lost 5 pounds in the span of ONE MONTH. I need help. Please. I weigh 109 lbs. After losing the weight.
