i am 18, female, 100 pounds, 5 feet.

i have a smaller appetite than before, i eat less and i am less interested in foods.

i do want to be smaller, but i do not think i am fat. my family thinks i am very small because i did lose 20 pounds since nov. 08.

i do not see the weight loss in me really

i do throw up my foods on purpose sometimes, not very often. i read labels on the nutrition information, i have a problem, i just do not like food, it is bothering me, and i want to be a little smaller. and i throw up now and then. i skip meals.

is this a eating disorder, and if so, what is it called?
