Do I Have an Eating Disorder? I don't eat much at all, especially at school. Whenever I do eat though I throw up. I am 175cm tall and weigh 54 kg but I don't see myself as thin, there's always somewhere I can lose weight. Occasionally I do excercise, I go for a 20 minute run every morning after I wake up.
I get dizzy and lose energy a lot too.

Some of the teachers at my school are asking questions, and even some of the kids are asking.
I'm too scared to tell my parents, and therefore can not see a doctor. I'm scared if I ask a teacher for help they'll tell my parents.
I don't know what to do. I don't think I'm so serious that I'm going to die, and I want to stay skinny, I'm just over the whole dizzy / no energy thing, as well as people telling me that my ribs are disgusting.

I've always been pretty thin though, and none of this started as a weight loss thing, it started because I just lost my appetite, every time I ate i'd get sick so i'd make myself throw up.

What do you think?
