Like people have for hundreds if not thousands of years before you, and probably will for time to come, you need to be patient.
If you want to be independent, then you need to save up money, get some resources, talk to your friends! Maybe someone can be a roommate and you can cut expenses. Maybe you can go to a university away from where your parents are.
Independence does not happen overnight. And no one will just hand it to you, because that's not independence. It's something you work on, not whine about.
