what do i do😭

im 18. i graduated highschool. i have my own car and a good job. my parents still arent happy with me. my brother is making my parents raise my rent from 200 to 500. i told them i was planning to move out next month. i dont know what to do. they are controlling everything. they hate my best friend. they dont allow me to go out past 11. they even drug tested me and of course it came back clean! i feel like i don't do anything wrong
