I’m so done with my family.

So this is kinda a long story. About 3 years ago my sister moved out when she was 17 because she got mad at my mom. She moved in with my moms mom (my grandma) which of course made my mom angry at her mom. My sister called CPS on my mom and the cops and everything all because she was mad. For several years I thought my sister and grandma were in the wrong for hurting my mom like they did. Things were never the same after that. Holidays weren’t holidays anymore. My mom was sad and depressed. She became angry and laid in bed all day demanding things from me. I was so good to her. About a year ago a girl at school (my bestfriend) which is now ex best friend started a rumor saying I was having sex for 5$ with both guys and GIRLS! It was so hard to make it through a day without being asked for sex. I got so depressed. I moved schools. But that didn’t work. So now I do online school. I would come home and my mom and step-dad would scream at me and tell me how I never do anything right and how im so disrespectful and how I was basically a nothing in the household because all I did was sit in my room and listen to music. I started to cut. I started popping pills that didn’t belong to me. I started thinking about suicide. I started remembering old memories like when my real dad sexually molested me. and how my step mom physically abused me. I went through hell but my sister claimed she had this horrible life whenever EVERYBODY in my family loved her. I only have one grandma and she was her favorite. She was my real dads favorite. To this day I still cut. I came close to killing myself about 6 months ago but I failed. I took a bunch of pills but they ended up pumping my stomach so I survived which honestly sucks. My mom still screams at me and throws things at me. She constantly puts guilt trips on me and cries telling me how I say she is a bad mother. We get in physical fights all the time. My step dad and I used to have an amazing relationship but that went down the drain. I feel like I have no one. I have a boyfriend of 4 months who I love so much and he loves me but my mom always keeps me from him. But its just getting so hard to keep going. I’m 16 and I have my own truck and job so I’m sure I could make it on my own if i moved out. I keep telling myself when I turn 18 I’m gone. I will not live in the same state as my family. and Thats the truth. I’m moving away once im gone im gone. Im not coming back. I’m just ready to be done with my family. Is that so bad…?
