How should I go about my current situation?

This is gonna be kinda for long so please bear with me. Also I'm dyslexic so if something isn't spelled right that's why and im sorry in advance.

I need help on how to got about the situation im in right now. So i 19(f) am currently fucked. I im trying to get my life together and i have been trying to get my life together since i was 15. A little back story here: so i was adopt it at three days old, along with my sister, who is three years old, my biological mother is a junkie an alcoholic. I was told that she did drugs and drunk while I was in her. Another side note about her is that she's mentally slow and is diagnosed with a lot of other mental health issues. i don't know who my father is, but from the way that my bio mom treats me, I assume dad raped her and that's why she hates me so much. I am the second oldest out of 4. But I do not live with my other two siblings. So I was adopted at 3 days old and let's call the lady Pam and the man Rob. So Rob is my biological uncle and he adopted me with pam, so that means his sister, it's my mom, there is no incest (that I know of). From the very beginning their relationship, was ass. And we were only adopted, because she was married into the family, and she couldn't have kids of her own. They never ended up getting married apparently and the relationship ended. My childhood was not great. There were good times but for the most part, it was shity.

Childhood:

So from a very young age i wasn't like other kids. I was diagnosed with ADHD and ADD, OCD, and there was another one, but I can't really remember it right now, but what i'm trying to say is i was fucked up. And form, as long as I can remember, i've been doped  up on all types of drugs. There was a point in time where I had to take ten pills a day just to be "stable" all before the age of ten. I can remember times where we wouldn't eat because she didn't have money for food so she would sleep with men to get it. There was also a period of time where we couldn't even sleep in a house because we had no heat. Now as for pam she used to take my pills. She also used to beat on my sister. There was this one time where my sister's eye add god's swollen, and I had a phone, but it wasn't on and i called 911, because my sister couldn't see out of her eye and with my Pam got home, she yelled at me then she took the phone, she threw it on the ground and it bounced back up and hit me and the lip. And continue to yell at me asking if I wanted to get taken away because the house was always junky, and they could've took it us away because of it.

There was another time where she was taking me to the mental hospital, because i either tried to kill myself or said. I was gonna kill myself. And while we were in the waiting room, we were arguing about something then I said, "well, then if it's so hard for you, you should have just given me back up for adoption" which then she proceeds to say "I tried, but they wouldn't take you back." That broke me. And she would never understand that the reasons why I had to go back to the mental hospital and keep going back. Was because of her in her actions. In her eyes, an adult can never do wrong. And im just a child. There was another time where she had to take me to a doctor's appointment and I was already up and dressed then when she came out, she was irritated and mad at me and she told me to take my medicine as I was getting app, she kept yelling at me and she told me to go get a bottle of water when I went to go get the bottle of water. She pulled my hair.It slapped me in my face. I was only 13-14 at the time. A side note about me is when I get my hair pulled or feel threaten I black out and start swing I just remembered looking at her not with such hatred and disgust that she just apologized and try to buy me food.Like that was going to fix the problem. She has done nothing but belittle me and my feelings. Always making me feel inferior to her.In her actions like what I do will never be enough. When I told her that her boyfriend was making moves on me.She told me she was going to kick him out i had just turned 16 when he tried. She never did, and he kept making moves and comments about me and my body until one day. It escalated and he raped me in her bed then he tried to rape me again but I said no so he tried drugging me and giving me liquor. And when she found out about it cause I didn't tell her my sister, who has no contact with her called her and told her. She was yelling at me and she told me she would kick him out. But before she did that, she can find it, he's in front of me and she did kick him out and we had to move, but she's still in a relationship with him. She still calls her baby, she still kisses him.She still pays for his food and everything else. But I can't even get her to turn on my phone so that I can get a job and get the fuck out of dodge.

What should I do?:

So now my questions are, what should I do. I am currently in Mississippi, but I stay in. Texas, she brought me down here so that she could get a break. I had got the implant, that goes into your arm and I started having complications. She told me she was going to bring me back so that I could get it taken out. That was in december. Also I have been trying to be independent since 15. I've been trying to get a job and get my own place since I was 15. And every time i've asked for her help, she makes up an excuse and or tells me she's going to do it, it never does. Then when I've given up, hope she tells me, oh, why are you so lazy? I tried to do this for you. I tried to do that for you, and you just don't want to get it done. I'm tired and exhausted. I don't want to be under her roof I don't have to rely on her cause she never pulls through. I'm tired. I've always feeling like shit while she thrives. I just want to have my own money.My own place so that I can be so sufficient in life. I have a decent, IQ. I'm very smart. I wanted to go to trade school to become a masseuss. But right now I just feel so hopeless.And i'm tired of hearing you're just like a mom, you'll never be sick just like her.It's that Thompson bloodd in you that's why your so fucked up. And I also know that she's been using my name on things and fucking up my credit. I just have no proof yet, but I remember things from my childhood where she would use my name on important documents or other things like cable orbils. I just need help on what to do. How can I make money? And get my shit together and leave her
