My best friend is in the hospital from attempted suicide. I'm kinda freaking out.

First off, hi, I'm Anthony, I'm 17 years old as a junior in high school. My best friend, whom I've known since 7th grade, just tried to kill herself by poping pills. I don't know what kind, I don't know many details, because the person that took her to the ER hates me and won't talk to me. I don't know what to do. I want to help her, but this is the second time she's in the hospital for this. The first time was more that she was talking about it, and she got help for 2 weeks but she hasn't even been back a full week and she nearly killed herself. I've seen your magical helping powers, reddit. I just don't know what to do. She means so much to me.

Update: I just found out that she took all of her anti-depression pills, some advil, and some anti-congestions.

And thank you all for the help. I'm quite glad I came here for it.
