why i'm so obsessed with my weight. i'm 5'3 and i'm 90 pounds. and thats not overweight, and i know that. all my friends and even people i don't know tell me i'm thin and look good. but for some reason, everytime i look in the mirror i feel fat. i try to excersise but it doesn't seem like that does any good to look better to myself. i feel like everybody is just telling me i'm thin and look good so that they don't hurt my feelings. i weigh myself atleast 5 times a day and i'm so paranoid that i look huge because thats how i feel. all of my friends weigh more then me but ithink they LOOK thinner then i do. i go a couple days without eating, or eating VERY little, then i'll go a couple days eating like two small meals a day but everytime i eat all i can think about it gaining weight. lately, i'll eat my two small meals and then throw up afterwards. i don't understand why i act this way or why i think i'm fat. can anybody relate?
