I don’t know what to do??

Hey guys, I’ve been in a horrible situation for years .. and I’m so sick of it. My moms boyfriend is emotionally abusive to me, my mom, and my brothers. At this point I’m done with it and I’m ready to move out and get a car ! But the only thing is I have no idea how to do! The first thing I want to do is get a car. I just don’t know the steps to do it. I don’t know if I can do payments ? Because I just turned 19 im working full time and I’m saving up, as of now I have 1,000, which really isn’t nothing. I live in Colorado which is super expensive to try to rent yourself! Can anybody please give me advice ?? I just want to get out..
