If your name isn't on the apartment lease, just move the fuck out. He isn't human, and if your mom is chronically ill, I'm sure she gets some form of government assistance and can get by without you living there. If you must, send her money, but don't live in filth. I know (especially if you're an immigrant?) that its hard for a woman from a family-oriented culture to strike out on her own, but you will not regret it, so don't wait. Find good, fit friends, focus on your school, and keep the toxic family relationships at an emotionally safe distance! For your own sake! And while you're at it, get verified ;)
