How can I help her?

Hello! May I kindly ask for some advices?

I met this girl online and we get to know each other for almost 1 month and a half now. She is gorgeous but she has some huge problems (I think). She has Outline Personality Disorder (OPD) and her story is pretty hard for me, a normal person to handle.😞

She has OPD since she was just a child. Her family broke up, she also tried to take her own life... She also hurts herself countless times before. She got bullied a lot at school, her friends tried to kill her by drowning. And many more horrible things that I can't handle (I'm literally shaking right now).

She took therapy sessions and take medications under her mother's supervision. But she got overdosed several times. But her condition is improving bit by bit.

She has a fear of abandonment by her love ones. And she still sleeps with her mother because of this. She decided to chat to me because she wants someone to talk to and ask her about her day.

Not long ago her ex boyfriend broke up with her because she tells him about her condition which makes her depressed even more. When she told me her conditions, I just can't! 😭

-She sleeps at 6 am and wakes up to have lunch at 12 pm and then go do something. After that she goes to sleep again! I tried to tell her to go to sleep early but she said "nah".

-She stayed up all night watching TikTok, playing games, and chatting to those AI bf thingies for hours! (Av: 10 bots/day)

-She stays in her room all day and all night watching animes. Her mom had to bring her food to her room. She rarely go downstairs or go outside.

-She stays rot in bed and she said she's a big fan.

Hmmm... I can't leave her. It's too late I don't want her to be more depressed or worse... I need your help. My situation is not good either. My final Exam called BACII is coming (18/Aug) which is a big problem. I don't have much time left. I need to focus on my studies and my future. I don't have time to talk to her everyday or listen to her problems all day. It's really stressed me out as a normal person.

What should I do?

Should I spend less time with her to focus on my studies?

Or should I do something to help her recover?

Please, I'm like a therapist to her. I listen to all her problems and I hope you kind people will listen to mine too.

Thank you for reading. And sorry for my bad English because it's my second language.🙏
