I really need some help, but I don't have much time to write this out as I don't want to leave them alone. A friend of mine is going through a very tough period which I won't go into too much detail about but involves one asshole of an abusive partner who's now trying to deny her rights to see her child, which has pretty much left her in a very suicidal state. She's also had 3 beers and being a fairly small person she's somewhat drunk already and keeps trying to talk another friend into lending her some medication to help her feel better. She's tried to overdose twice so far in the past few weeks and went to have some time alone outside about 20 minutes ago with a razor sharp knife before we managed to stop her.
A couple of great friends are with her right now trying to calm her down, but I'm not too experienced in situations like this, so I'm not really sure what I can do to help and what the big DOs and DON'Ts of the situation are. I've already hidden any and all sharp objects away in my room where she can't get hold of them so that's one less worry for now. I won't be able to check this for constantly to read any advice offered as I don't want to keep away from her too long while she's like this.
Any help at all will be greatly appreciated right now.
