I'm genuinely tired.

First I wanna say that I speak spanish and my english is not that good.

Since 2013 my sister (24 F) has been really harsh to me (21 M). We lived in a very small house in which we all can hear others noises and stuff. I was around 12 and all my friends did like to stay up late night playing games. I never used mic, I've ever played making near to no noise at all. And every night, she will wake and treat me like trash, slapping my headphones out of my head, waking my mum just to make her tell me that i should turn all off and go to bed (my mom was ok with me staying up late night). Living like this until 2020.

Been always like that until everything turned to worse this year, she fell in love with one of my best friends (she did make him her fp or something like that). He rejected her, and of course, she did not accept anything he said and she started to hurt herself, making "suicide attempts", and falling into a "loop" in which she threw hate to all my friends (also her friends), feeling worse and tried again to suicide, and this never ends. She also has debts and I tried my best to let her know how all will end, every time i tried, she would end trying to suicide or just won't listen anything I say.

In order to get over my friend, she started dating other friend of mine which she didn't like at all and even she did make fun of him very frequently. She is just playing with his feelings, i feel really bad on what she is doing, at the end of the day she does the same that my friend did to her (but even worse).

My family is really broken now, my mum doesn't know what to do, every time she tries to hurt herself, she just make this never ending loop worse, with more pills, with more debt. I just don't know what to do, I'm on my first year of college and I really can't work full time and just go away, I don't have the time, money, and it just feel so unfair to me and to my family. She is going to therapy, she is on meds (really tough meds) and this just makes everything worse. She isn't making any better at all.
