I agree completely. They won't change, and they don't care if they're disrespecting you: they just see it as "their house, their rules". In fact, they probably see you as their property too, and treat you as property instead of an independent adult human being.
Make yourself a long term plan to get out: save up, work two jobs, start looking for house-shares. Onward and upward!
