If your 16 and cant stand living with your parents anymore because they lose their minds over the smallest stuff like leaving the backdoor open if i went to get the mail can you leave your parents?

Suck it up until you're 18. Make decisions NOW so you can make that a reality. Get a job, a car, and save up some money. I was in the same direction but decided to go to college instead, even though I had done all those steps at 16. 2 years is nothing, good luck though.
