please search the internet for support groups in your neighborhood. I found one for $10. per week and if I couldn't have afforded that, it would have been ok. There are YMCA programs that sometimes offer free counseling, as do local colleges. Even Churches. Anything. But slitting your wrists is definitely not the answer. YOu can beat this but not by yourself. And if no one is willing, you need to search for help for yourself. Also check out Eating Disorders Anonymous, they run meetings all over the country.
Don't give up.
