What do i do with myself? Do i move out when I'm broke?

Nov 19 I'll be 20 and I've been going through a lot of sh*t that I shouldn't be going through. I had a forbidden iphone from a friend (I was his secretary while he was out of country) and my parents found it and they didn't like the messages I was sending apparently. The messages were about telling my friend the stuff that I was doing (like sneaking out, answering questions about my religion and other stuff). Now I'm grounded and I'm not allowed to associate myself with my sister (my closest friend) because I might get her into trouble. Yes I was going behind my parents backs but that's because they give me no freedom! I don't know what to do with myself. On top of all this I just recently had a car accident that left my car undriveable and me broke, so I just get my mom to drop me off at college and I stay there until I'm bored because I don't want to go home. I'm only allowed to see people that go to the same church as me bcz my parents think it'll affect my religion decisions. Why?

You are living under their roof so stop complaining. You are always welcome to work full time hours on top of that and have your own place.
