I started not eating very well abouta little over a year ago.. i was 197 pounds at my heaviest. and i was 13 years old. Now i am 15 and i weigh about 138 pounds? I started not eating or drinking but every other day at the least.. i've skipped up to 4 days.. i've been through hell trying to stay awake and stop blacking out.. I feel so fat all the time.. everytime i eat, i gain 5 million pounds and then i can't eat for set amount of time.. i want to be pretty.. i want to be skinny like other girls.. I want to be able to have confindence to be able to talk to people and i think maybe if i like my body.. if i get skinny and i become pretty.. maybe i will have that confidence.. but it's affecting my health doing this.. but everytime i eat i feel so sick.. i feel like i'm going to purge and i don't understand it.. can you help me?
