Would love to help someone solve their mind related issues.

I'm 20 and during school break one night decided to masturbate to some porn , and I came across this video and the pornstar looked alot like my mom , the actress had the same hair style my mom always wears and the pornstar was giving oral i like watching oral but she looked to much like my mom so I fast forward to where the porn star is riding the male pornstar and this reminded me of when I was a kid and my mom and her boyfriend would lock themselves in a room for hours and I thought to my self when I was masturbating that this is probably what they were doing , so I imagined the porn stars doing it in the room and this turned me on, but then I thought that it was gross cause that's what my mom and her boyfriend were doing , so I focused more on the porn star lady cause I just wanted to finish and go to bed , but now I feel like I jacked off to my mom and her boyfriend because It did arouse me a little but I tried finishing to the porn star , I feel sick , I hate that it turned me and that I didn't stop masturbating , I feel horrible , I was never attracted to my mom and I mastorbated that day because I was horny not cause I wanted to jack off to my mom but that video ****** it up , now I feel ashamed , this is serious , please HELP!

Hello everyone!
Some bad things happened in my life lately, and i really don't know what to do anymore. And i can't tell anyone and i really need help... Please help me.
I'm a 16 year old girl. I have an older sister who is 20 years old, but lives in another country. I also had an older brother but he died and i'm the youngest kid of my family. My parents were always good to my siblings, but they always abuse me physcially and mentally. My parents divorced when i was 11 and i started to live with my father. But he was always beating me up, throwing me stuff and yelling at me, saying bad stuff to me and i was really depressed. And everyone was bullying me in school because of my look and it was making me really upset and make me hate myself.
When i turned 13, i started to live with my mom and she got married last year. But she changed a lot after she got married. She started abuse me, she was always talking about how ugly and stupid and lazy i am etc. Then she started to hitting me.
One day my mom and stepdad went out for drinking (they are drunk most of the time already so...) and they came home at like 3 am. And my stepdad tried to rape me. Then i called police, they took him to police station but he didn't go to jail...
After that day, he started to hit me too and my mom wasn't saying anything. I had a lot of scars and bruises on my face and body.
And then they kicked me out from the house because they said they can't take stand me anymore and my dad said he doesn't want me in his home so i'm staying at my friends home for now.
I feel really bad. I wanna run away from all of this and I wanna die. Nobody really cares about me, even my parents. I want to talk to my mom but I can't do it. I don't know what to do.
Btw i'm sorry for my bad English because my first language isn't English and i'm still learning. Thank you so much for reading..

when I was a child I used to force myself into peoples lives. I used beg for attention from everyone even random strangers. I couldn't tell when I was being rejected and hence constantly acted dramatically. the problem is that I cant tell whether im still like that and I don't know why I do it. its like I have no control over how I act or who i open up to. I open up to people ive just met and I end up feeling worse cos I think theyre laughing behind my back.

So, my step brother took the plea. What now? What happens next? I have been preparing for the worst, and now I'm suppose to be happy? I don't understand.
