You need to leave.
My mother and i(at17) left my father, my mother was making $12 an hour working fulll time. She found a program called Affordable Coalition Organization that lets people with low income to medium income buy a property WAY cheaper than its market price, research for this in your state. We saved up 4,000 between the two of us and she served him his divorce papers, we moved and never looked back. There is a way out, believe me. As for making money, if you can sign up for Lyft, it's about $18-35 an hour and you can work when you want or just need extra money. It helps me a LOT.
You need to leave him no matter how hard it will be. Trust me. Your life is not never ending, when will you start living for YOU?
