Why don't i get hungry?

i never get really hungry but i only eat when people tell me to or just give it to me. if i eat half a sandwich, then i become full. is this weird? my weight is like 120-125lbs. i have no idea how i lost weight b/c i used to be overweight like almost 140...

:/. my height is 5'1. i want to eat every 2 hrs [to get my metabolism fast again] but i forget b/c im at school.

thats how it is with me too!! my doctor said it was my enemia(sp?) which is iron deficiancy in the blood...but i think shes lying... then again... im paranoid... but get checked for enemia...that may be the problem...or depression...

i do get depression. and i have insomnia. my acupuncturist said i have an eating disorder [not like anorexia or bulimia]

maybe u have a small stomach??

i do have a small stomach.
