What to do when your parents are strict?

Basically I dont have a lifee. Like. They dont let me go out. Im always at homee doing nothing. The only let me walk around the neighborhood sometimes with my friend. The only way i can have fun is if its with church people.. Theyre really religous and theyre trying to turn me into them. Im not religius... Like i dont believe in it muchh. And theyre so strict about my clothes. Like they dont like me wearing pants just skirts.. my dad keeps saying hes gonna throw them out. They dont trust me at all. I cant do anythingg ! Theres more but i dont want to make this too loong. Im 15. And summers coming soon... i want some freedom. i dont know what to do.. if this keeps up. Sometimes i think i should just run away to teach them a lesson.. And sometimes i think ill get back at them when i turn 18 and ill do everythinng they didnt want or let me doo. I used to think of suicidee... bc i feel like im on lockdown. its just school hom church. and im getting older and watching everyone else get theyre freedom and im just there.. today i talked to them about trust and freedom and they said when im 20 theyll stop being strict. so i told them im going to college when im 18 and they said theyre still gonna be strict?! idk how. but yeea.. any suggestions? what would you doo... sometimessi feel like im gonna explode. Thats some of it.. i dont wanna right too much.. im in a hurry bc hell be in here any second asking what im doing..
