Hmmm my first post other then in the introduction area and its a problem.. hmm *wonders if thats bad* awww well.

Anywho, onto the troubles. My best friend has alot of problems, she goes through a fair bit in her day to day life so i'm always worried about her. But I'm not here to talk about alll her problems, though i'd to get some advice on how to help her with them all sometime, i'm just lookin for a lil help on one of them.
She recently told me that she'd been making herself throw up. She didn't say if it was often or anything but i'm begining to think it is. She was already majorly skinny so i'm really scared for her she also starves herself sometimes . Personally I think its all her boyfriends fault. He's a real jerk and he's bloody messed up. He has this obsession with stomachs and stomach growls. All he seems to care about is her stomach. its really sick... He even asks her not to eat to makes it growl. And he used to ask her to make herself throw up. He once asked her to go for a week without eating and she fainted she couldn't walk or anything. So now she thinks theres something wrong with her so shes doing this. She only weighs 51kg and shes tallish so she's definatly not fat. I'm trying to get her to stop but i dont think its working. I was begging her to eat today and she just wouldnt. I just don't know what to do Any advice?
