Are you in a position where you could live on your own? Do you have the right kind of skills to be able to provide for yourself for the rest of your life? If you do, then move out as soon as possible and make your own way in the world. Get a room mate if you need to, cheap apartment, anything is preferable to abuse.
The only time the abuse will ever end is when you yourself stop it, and that can be really hard. I assume you are seeing a therapist. If you are, then you should bring this all up with your therapist. I know this sounds drastic, but have you ever considered taking the abuse public, maybe even pressing charges? I am also a survivor of childhood abuse and grew up with non understanding, incompassionate religious zealots. When my mom used to catch me dressed up like a girl, she would sit me down on the kitchen table and I couldn't leave and had to sit there for hours while I was constantly insulted for hours on end. At the end I would be drowning in my own tears and didn't really even want to live. But I did. I did eventually tell my parents all the abuse and shame that laid at the feet of a child. I could go on for hours at what they did to me, but the fact is, I am still here, I am not afraid to tell my story anymore because I am the victim not the abuser, and eventually I was able to confront them with the abuse as well. In many ways, in going through this with my therapist I began to realize that what my mother had done to me was worse than the sexual abuse I had suffered. If I saw them now, I would let them have it for hours, maybe it might even be some satisfaction for me as well.
It can be really hard to confront abuse, I know myself because there is a huge power difference, and these are after all your parents. Maybe they thought they were doing the right thing, but abuse is abuse, and it needs to stop, and you being dead is not the right answer.
