Hi. I'm 15-year-old female about 136lbs and I think I might have an eating disorder. Maybe not a disorder but a problem. I never really eat a lot, even less now that schools out and my sleeping pattern has changed, but according to my mom I've always had a small appetite even when I was a baby. I feel nauseated when I eat to the point where I'm full so I don't like to eat a lot. Is this an eating problem?

I'm not sure if these other "symptoms" count for anything but I get frequent headaches, I'm almost constantly experiencing palpitations, the occassional feeling of vertigo, and my legs fall asleep very easily.
