I suffer from Bulimia too, And it does suck. I havn't had the disease as long as you have- I've only jad it for 1 year. I can't really give any advice to you- Though i would really like too. I don't understand it that much and you probally do because you've had it alot longer than me. I guesse the only advice i can give to you as being someone who suffer's from it is:
Dont look at food as if it's something bad- That's what targetted me into being Bulimic.
The reason i started to be Bulimic was because of my friend's being skinner than me and i felt stupid being the big one. So i threw up and kept doing it. Im really not very good at this kind of thing because i dont even understand it!
But i know how you feel.
My life is ruined and i do not know why i am not dead.
Im 18 and it has been the most biggest mistake of my life.
