<human>: So where do I start... I've been best friends with this girl for around 3 years and on/off relationship as well. We're both 19 yrs old. She's the most genuine and good hearted person I've met and we've been through a lot together. Extremely creative too. I'm not sure when I found out but I've known she was bulimic for at least a year. She's been in programs for it and dealt with it for over 4 years. Her parents, doctors, and I are the only ones who know. She wont express it fully to her parents but honestly I don't think they'd do much, they've known for 4 years. She explains it as not being image obsessed anymore but just having an addiction or something to make you feel like you're disappearing. I used to be quite into drugs so i can really relate to this feeling but the only way i found change is really hitting my own bottom, i really don't want her to hit the bottom of this. I really should've gotten educated on this a long time ago. Here's what I've been trying to do over the last year:
- I will tell her I think she's beautiful but I won't go over the top with it. 
- I make her talk to me about what she's feeling if I ever hear self conscious things she says. 
- i get her to consider inpatient/outpatient but the people who work at them always scare the shit out of her. (We've actually been through the same outpatient system, same building, different things but they freaked me out pretty good too)
- try to get her to eat but never stress it 
- be as comforting as i possibly can

Overall I try to get her to just be as open with me as possible and get her to talk to me whenever comfortable. But i really don't know much of what i (or anyone else) can do. So if anyone has any advice? Or personal experience they wouldn't mind sharing... PLEASE! Help me out man. I don't want to loose her in any way to this. Thank you.
