I don't like it here

My sister just moved out from my moms and stepdads house. I've always lived with her and I moved to my moms to live with her. Now she is gone. My step dad is talking shit about her everyday. And saying my going to end up like her. She's had sex and almost pregnant and done drugs. Apparently I'm destined to end up like her. I want a good life I've had it planned out for years. Graduate from high school. Go on to college and become a personal trainer. But not to him. I'm going to be a teen mom and drug head. I don't wanna be here anymore tbh. I wanna go back to my dads even tho we don't talk anymore. My step dad is always putting me and my sister down like we are dirt. He says he does love us and does this to us so we won't let it bother us when someone else says it. I go to my room to block him out but he talks so loud I can still here him. I go on walks to get away from him but I still have to come back to this shit. I can't leave tho. I have my dog, my running future at my high school, and my boyfriend and friends. I don't know what to do anymore. It's to the point where I stay up at night crying because he makes me feel terrible. I hate it here. I want to go away. I want to move. Mom knows how he makes me feel. He is mostly drunk when he does this. EVERY NIGHT. I stay in my room all the time now I don't come out. I want to leave my house when he gots home so I ask if I can hang out with my boyfriend and he says no. I ask to leave for an hour he says no but mom says yes. It's annoying and I hate it.
