suicidal alcoholic friend calls in the middle of the night

My best friend who always said he loved me, dropped out of school after 1st semester has became a horrible alcoholic. He already was taken out of school and put into a hospital because of depression, cutting, and has been declared a schizo. I haven't seen him sense last October of 2009. He just called me twice saying he was drunk (like every night) and that he was holding a knife. He doesn't want to drink any more but when he tried to stop it hurt and he just threw up many times. Saying he had made a list of things he wanted to do before he died, and that one was to see LMFAO yesterday live and concert, which he did. Another was to call me and tell me he loves me one last time and that he wanted to marry me, being with me forever. I knew he was drunk and didn't want to believe anything he was saying. We talked for about an hour and he kept telling me I didn't understand what he meant. And I don't, but I'm worried for him, cause we both loved each other back at school. He hurt me soo much then, I had to wear bandages around my wrist and thighs for cutting. Once he forgot about me I quit and wont do that any more. But I'm very scared for him cause hes almost committed suicide before. I don't know what to do for him. He needs help, now, before something happens.

He has serious issues and you are considering joining him in his misery?

Can't you call 911 and tell them your friend is acting dangerously and you think he is suicidal? They will send police to his house to interview him and take him into the hospital if he is drunk and confused or worse.
It's better then you trying to help him yourself and getting hurt again. I don't think there is anything you can do for him hun. You have to let professionals take care of it from here.
He will be angry with you of course. But when he is healthy again he will get over it and may thank you.

Yeah the only thing you can do right now is get help for him call the crisis hotline for him.Keep posting.

Mass, SERIOUSLY, you've gotta call for help. He's suffering, I know, but you are too, and clearly, if you get him help, you'll start to feel better. He needs to be in safe hands, and the reassurance will help you lots..
Don't feel ashamed to pick up the phone..it's not an easy call, but the most important and necessary one.

Hug for you both hun, stay well..
