What is this called?please help!?

What are you asking exactly? I mean, it seems like you already know some of the problems of anorexia, and you know the symptoms. Are you asking whether or not you have it, cuz I definitely think you do. You don't have to be oober skinny to be anorexic. And some people it takes them a while till they get to the point to where people can really notice the signs. Besides you not eating much, what are the other symptoms? I think it's possible you could have it, but I don't think you're QUITE there, but if you don't get the help you need now, then anorexia is right around the corner. Please get some help! See a school counselor.
