I don't know what to do! I'm 13 years old and we are just about to start school again but I'm really nervous! Every time I eat I feel sick afterwards, and I'm scared I'm going to throw up or something, but I haven't so far. The less I eat I don't feel as bad, but I still don't feel good. It started about June. Ive  looked up stuff of what it might be but none of them really fit what I feel. I don't want to tell my parents in case there is nothing wrong, but I think there is. I was just wondering if anyone had any ideas of what it is??? Or what I should do?
