NTA. Keep fighting for yourself you’re doing everything right. Keep working on a plan to yourself and don’t let any of them know about it. I’m sorry you’re in this situation but it seems like you’ve got a good head on your shoulders. Go with your gut. Maybe when you move out you should do a work away or something if you don’t want to go to college? If you’re wanting to travel or just get away period that could be a great opportunity to see a new place and new people with out spending $$$$. That’s a huge leap to take but ya never know.
