I'm 19 years old and I still have a sitter. What should I do?

I'm a 19 years old guy, my parents are very very very strict. They have cameras in every room (mine included) I have to ask permission for basically everything like studying, going out (which is almost always denied) watching TV, even for freaking going to the bathroom! And when they aren't home all of the things listed fall onto a babysitter, they have never called her a sitter, but that's basically what she is. Talking to them is almost impossible, what can I do to make them understand this situation is almost unlivable for me? I have zero privacy and no friends, how do I make this situation better for me?
