There's this girl I've known for maybe half a year now, for the past few months we've been sort of playing around with the idea of dating. I knew right off the bat that she had some issues, at first I thought it was just low self esteem as she told me, but the past month it's gotten a lot worse. She's been shutting herself in a lot more, and I now know from her that she's started taking medications for depression, and is also suicidal. We were working around that, but last week it just went downhill fast. Something happened, and she just won't tell me what's wrong, she just stopped talking to people. On Wednesday she told me she attempted suicide by taking all of her pills at once, but threw them up, and how some guy made fun of her for cutting herself. I just don't know what to say to her, because sometimes she's happy talking to me, other times she's not, I can never tell until it's too late. She's said some things about us that makes me conclude our relationship is now on the rocks, but I'm just scared for her. She just says she wants to be left alone, so I told her I would stop texting her for a while. I'm scared because I know I can't just be content leaving her to her own devices, but I don't know what to say to her, I've said everything I can think of. That I'm her friend, that I want to be with her, that it would hurt me and many others so badly if we lost her. I just don't know what to do.
