I (14m) noticed that nobody loved me, my gf left me 5 days ago, she used me like a sexual toy, she didnt want to have a relationship with the same amount of affect from each other, she just kept me apart and talk with other people, everytime I tried to say to her that we need to fix our relationship she just played the victim and never changed, every time. She did me really depressed, now I hate her.

 We were good friends before being together but something has changed on her, 3 weeks ago I noticed she was talking to a new guy, she 5 days ago left me without any explication, I cried and cried and I had attempted suicide (she was just the BOOM of my problems, I have a lot of problems, not only with her) I was at the hospital 2 days, yesterday she and my friends visited me to "support me and take care of me because I attempted suicide" but they only said hello and kept me apart and they were talking and laughting in my room while I was crying, they dont care about me, I feel even worse now, the only thing that keeps me relaxed is playing guitar.

My parents dont seem to care, they only keep going like nothing happened, my parents used to fight a lot weeks ago.

Now I cry every hour, my life seem so meaningless.
