Fifteen going on sixteen.
Suffered from Binge Eating Disorder when I was ten and it left me overweight. Been wanting to change that for a while. Then I discovered I have an unrelated medical condition which pretty much restricts me eating most of the food pyramid: sugar, salt, fat, citrus, caffeine, etc. And it gave me that extra push I needed, I guess.
Tho living in a boarding school makes it relatively hard to control what I eat.
