Convince my parents to let me leave/move out/do anything

Made a post last night and a billion other posts on my parents. It's too much to put in here but enmeshed is the word I always use. Like extremely enmeshed.

I (f19) need to move out but they won't let me. "You're an adu-" stop. Everything I have ever done is with their approval and I H. A. T. E. dealing with my mom's emotional gaslighting and the reason i am so far deep into this is because i just CANT deal with her, i will just give in to maintain household peace.

There is no such thing as me just leaving or running away. I work with them, me and my mom have to go on business trips together. I'm not quitting my well paying stay at home job. I have a 16 year old brother I am not losing contact with. I just need a way to covertly get them to stop being so controlling and stop wanting so much access into my life. I don't have any friends. I dont do anything. I cant leave the house without being interrogated and if I don't tell them exactly where I went or god forbid turn off life 360 immediately the assumption is I must be a prositute doing drugs in a dark alleyway. I'm the world's most normal person. I dont do that shit and I never have yet this is exactly where it goes when I dont give every detail. I'm a liar in my mom's eyes. Almost every other week she brings up how much I "lie" (????). She's told me how my dad thinks I am a liar too. I'm always told that I am being a victim if I bring up how absurd the lying accusations are. Idk how im making myself the victim when I explain my circumstances to anyone and they are SHOCKED.

The worst part is is ive been Grey rocking and now my life, to my parents, is so uninteresting that now the deal is "you can't leave until you have a plan for your life" (see last post) I DOOOO I just don't need to tell you every waking thought I have for my life.

HOW do I go around this, how the hell do I leave here and gain freedom without losing contact with my brother. And no, I cant tell him where I am going but not them, they will interrogate him too and he doesn't deserve that. Please please help.
