I would always recommend trying moving out for university. Even if it’s just down the road.
Better to try it and see than deal with what-ifs and resenting your family even more.
If you move out and hate it then moving back wis always an option and you might find that your relationship with your family changes having left and then returned (you might appreciate them more, they might appreciate you more - by moving out then it might force them to start treating you as more of an adult etc etc).
It’s not a golden bullet and moving out is difficult but you’ll learn more about yourself by trying it. Well worth the investment. Plus you’re likely planning to move out anyway at some point - delaying that until after graduation isn’t going to make anything improve sooner.
