I agree, try to find a place outside your home that's less stifling.

I'd also recommend therapy or counseling. I know it's a lot to ask of yourself to spend the money and time on it when you feel so drained and broke, but a good therapist can help you with things like changing how you react to your parents in a healthier way, finding ways to budget your time & changing unhealthy habits (you mentioned twice you don't like spending so much time scrolling), and even how to budget money so you can move out sooner. They aren't necessarily only 'Sit On Couch Talk About Feelings'. Therapy is a great investment in yourself, you just have to find one you feel comfortable with and who really helps you with what you need.

I do understand that it can be daunting to find someone to talk to, so I recommend doing a search and reading a few good articles on how to find a therapist that works for you.

And I'm really glad you reached out. That can be very hard to do in any situation, let along one as frustrating as yours. Be proud that you want to make progress and are trying.
