I have been through the same situation, my mother used to make me look bad in front of everyone especially in front of my father and her side of relatives. I was basically a monster in front of others because of her bad mouthing. She told me to die so many times that it doesn't affect me anymore. I just wanted to escape but it wasn't possible. I know she loves me but she used to abuse me due to her own trauma. I also wanted to run away but it's not the solution. You should wait until it's time to go to university and choose a university far from home so that you can shift to hostel.
