Hi.I have a few tips for you to help you:
1)Don't give up hope in yourself. Anything is possible if u really set ur mind 2 it.
2)Don't listen 2 what other people say. It may be hard (I know), but we here care about you, know just how you feel, and really couldn't give a **** what you look like.
3)Try not to get too down. I eat when Im depressed, and thats probably the same for u.
4)Whenever u have a craving, here's what I do: mix about a teaspoon of lemon juice (maybe less) with a large glass of water. Its a way to trick ur stomach to think that u are full.
5)Talk to your parents and get them to let u talk to a doctor. Your doctor should be able to give u a lot more advice and help u a lot more than I can.
Hope I helped.---Todd---
