Advice?

I'm a community college student living with my mom and her abusive fiancé. I have no one to go to and I have a small dog, too. What can I do? I'm currently unemployed because I'm taking a lot of credits so I can finish faster and get out of here. But I need a new plan. Advice? I'm 20. And I don't have a car to even move my stuff. Please help me? I don't know what to do
