7th grade - Detention

On the last day of school in 7th grade, I got detention, because I got in a fist-fight with my Ex-Best friend. My dad was picking me up from school that day and a little background about him is that he gets very aggravated easily so when I came out of the building, he was furious. When I told him that I got detention as well he got humid, I mean he was MAD MAD, like he sped down the highway, swearing at me, calling me slurs, ect... While all of this was happening I was texting my mom. He asked me if I wanted to walk home because I couldn't stop crying. I opened the door and tried to get out of the car, but he became even more furious because I even thought about it. He was so mad he took my phone and my mother noticed that I wasn't texting her back so she called my father. She told him to calm down and he said "No, this stupid bitch got a detention because of that girl we told her to stop hanging out with" My mom said "Don't call my baby a bitch" and she left work early to come home. My dad took everything and by the time she got home they got into an argument as well. She was like " How dare you talk to my daughter like that" and he was being a dick saying "She's the dumbass that got a detention" and my mom had enough of his bullshit, so she told him to leave. He went bonkers and he started coming towards me and then he grabbed me by my neck and pinned me up in the air against the wall, practically strangling me. My mom absolutely lost it and she was like "get the fuck out of my house now before I call the police". He started crying hysterically and then, she kicked him out of the house. She took me aside, comforted me, and told me to call my therapist. After I talked with her for about an hour, my mom told me to pack my bags and she took me to my grandparents house, which I would stay there for 2 weeks until I came back home on father's day.
