First of all, I'm sorry if I'm posting in the wrong section of the forum.

I'll try to stick to the point although I'll admit it will be difficult right now.
I have a friend. We're really close, I'd say, and we know quite a lot about each other. Today we were out and she drank a bit too much. Some of the things she confessed to me with I knew already, but some I really didn't and I honestly didn't know what to say or how to help her. Again, I don't really want help for myself right now, I want to help her, but I don't know how.

(We're both only 17 btw.)

My friend has had a really rough life. Her father used to beat her when she was younger, to the point where she was almost unconscious. She was bullied. Insulted by her teachers. She's been the victim of rape, twice. She told me how she will just use people and then ditch them and that she don't think she'll ever be able to change that, as that's who she is now. She's made many, many mistakes linked to commitment, sex, and other aspects in general before. She attempted suicide this year in April. She told me how she wants to die but is not strong enough to take her own life.

She admitted to me earlier she has a mental disorder but she doesn't take her medication due to weight gain the pills give her. I tried to convince her to take it but she just wouldn't listen.

Today, she told me some of the things I know for the first time, and I was stunned. She told me she believes she doesn't deserve to live. That she is a horrible person. That she won't be happy until she will stop breathing. I managed to stay calm through all of that and be there for her as she told me. Later when we were going home she told me to not touch her and to just go home and leave as I left her in front of her door. Through all of this, she was drunk.

As she confessed to me, for a brief moment she told me how she thinks she deserves better, but then she went back to saying that due to her mistakes and other things, she only deserves to die.

I really want to help her. Really. I don't know what to do. I realise this is very serious and I admit that I don't know how to help her right now. Please help me and give me some advice on what to do. I really want to help her but I don't know how and I can't take that. Even writing this, I feel like this is my last resort.

Please. Thank you for any help.
