😔😞😩I'm Nothing But a Walking Mistake

I just cried for because of the stupid mistakes I did when I was 13 I am now 16. I had sex with someone basically with no consent (I blacked out)  found out I had an STD a year later, blacked out once again at the information I got from the nurse so I couldn't hear her when she told me to pick up my medicine. So I had for another year and had sex (with the same person when I was 13, because I wasn't aware that he was the one who gave me an STD till I was 15 about be 16). I got a check up last year, and I was told I had the STD now this time I the medicine but then had sex again with someone when I had it so I got it right back I believe (Most likely) and now I'm 16 and I feel as if my life has no meaning to it, my father left me all alone and I'm his only girl so it was hard for me. When my mom got married I become a very angry child, I'm always mean for no reason. I can't help comes out my mouth when my siblings ask me anything, I always answer very angry. I call myself having 2 personalities. I use to leave out the house and come back 2 days later because I guess I wanted attention and I was just acting out. But I didn't start acting out till I lost my virginty. When I was little I use to get bullied. On my 9th birthday NO ONE came to my birthday party every family my mom called said they were doing something else (I felt so sad) my own father was even to busy for me. So went and to hide in my closet and cried. Every guy till this day uses me and i let it, I have no voice. No one likes me for me they get what they want and leave and I sit and wonder what have I done? One guy said that he regrets meeting me out of nowhere. I just clocked myself because I want to just die but the memories and thoughts of my baby brother keeps me from doing so. I often ask God why me? Why? I might never have kids (because of the STD). Why was I so stupid at age 13? BIGGEST MISTAKE OF MY LIFE! And I'm truly paying for it, I just want it to end.
