@Kayster ,
I grew up in the 70s, where there was just 1 phone line. And I also had to let my father catch me in my bra to get him to quit barging in my room without knocking.
So I hear ya.
Sometimes, people can't be told; they have to be shown.
Are you responsible? Getting homework and chores done? Doing your best in school, even if it's not straight A's?
Then you're fulfilling your end of the bargain. And some privileges should come with that. Because otherwise, you're being treated like you've been grounded. It's the kind of treatment that makes a person wonder why you should bother doing everything right, if there's no carrot to accompany the stick.
I think you may need to sit down with them and calmly demonstrate (with your report card in hand, and photos if you've got any) just how much you've been holding up your end of the deal. And, you're not super young anymore, and would like for their treatment of them to better reflect your maturity level.
But I do caution you. If there's an old incident in your past, or in an older sibling's past, then they might not budge. Sorry, and I know how unfair that is. But from their perspective, they may be terrified that you'll be attacked or drop out or whatever
There are also cultural issues which may be at play. A friend of mine is of Indian extraction. He writes great urban fantasy and his first traditionally published book is coming out this year. It's being published by an extremely picky publisher called Tor. The guy is pals with Jim Butcher and Brandon Sanderson, two of the biggest players in urban fantasy today.
And.... his parents still pretty routinely nag him about not becoming a doctor or a lawyer. He's also IIRC in spitting distance of age 30.
So... recognize that.
