Wall of text ahead. TW for suicide.

Alright, so we're both 16, I met her on May and we clicked instantly, and we decided to start a relationship. All is good, we're both happy, apparently she was going through rough times and I gave her confidence and will to go on and stuff. She has a sad past, due to a family member that abused her and caused her a lot of problems. On August 1st, she says she wants to break up with me, but doesn't leave a clear reason. I grief a lot, beg for her to return, and 1 week later she tells me that she was actually feeling really depressed, and then she revealed that she suffered from clinical depression and this took her to break up with me. She seemed to be getting better though, so I just say goodnight and went to bed.

The next day, she makes a suicide attempt.

She fails, they take her to an hospital and keep her there for a few days. A friend of her updated me as the situation progressed. She returned on a Saturday and tells me she's feeling a lot better, that she wants to go back with me, feels sorry for trying to leave and that she was diagnosed with BPD, due to the abuse she received from that family member. She says she'll get help at a special school and that they'll give her meds to get it treated.

Now we try to go back to where we were. She acts somewhat weird, not talking much, but didn't seem sad after all. She doesn't talk to me for a few days but then comes back telling me she was just really busy, and then I see the same person that she was before all of this happened. I thought things were getting better. 

But then she doesn't talk to me for two days, and on past Thursday she tells me to leave her alone, put her profile black with a "..." for name. I got really worried so I messaged her everywhere I could, until she showed up last night and told me that life was shit for her lately, that she left everyone (me included) except for casual conversations, that she feels as if she can't handle herself, that she's going insane, that she's scared. Apparently this started some days ago when she had to walk 4 miles in the rain, and yesterday her mom broke in tears because of the suicide attempt she tried to do a few weeks ago. It was crushing to see her like this. I offered her help and comfort but she just said she'd go and said sorry. As far as I know she just went to lay on bed to listen to music and/or smoke weed (which she claims helps to calm her down) and then went to sleep because it was like 12 AM.

She mentioned a few other things. She said she won't take me back (I guess she broke up with me but I kind of understand, I don't want to worry her about our relationship in a moment like this, she's likely to change her mind after she passes through this, plus considering she started ignoring her friends too...). She also mentioned that they didn't give her any meds, which is strange because she was supposed to get them two weeks ago, she said she'd get them "within a week's time" so I'm begging it's real soon.

Now... look, I can't claim to know how she feels. I've gone through few depressive times which weren't big, I obviously cannot understand what she's going through. I just want to be a supportive partner. Ever since she attempted suicide I worry a lot about her and I don't want to lose her. She told me a bit about BPD, she sent me this when she got back home from the hospital, which seems to be a pretty good description of what happened to her recently:

As in, she's isolated, doesn't want to see anyone, feels anxious and depressed. Now... what am I supposed to do to help her? How do I approach her? What do I have to say in order to make her feel comfortable and less worried? Would these meds she's supposed to get help to prevent a situation like this from happening again? A friend told me that I have to leave her be for some time until she recovers so I'm doing that for now. I left her some encouraging messages, telling her she can count on me for anything and some other things. I won't bug her... but I'm still worried. How long does this usually last? It's been 5-6 days. Should I be concerned about her attempting suicide again? I don't think she'll do it, she knows she'll destroy her mom if she does so. I'm sorry if all of this sounds naive or ignorant, I just don't want to screw this up... she means the world to me and I don't want to see her hurt like this. Thanks for reading
