My mom is too strict! How can my brothers and I get her to back off a little?

Sorry she is the boss until you are out own your own and paying for everything yourself. My mother and father separated when i was young i lived with my mom only not many restrictions i did what i wanted got in trouble and wound up in reform school for a few years at age fourteen. You think you had no freedom i was under complete control 24/7.it was a good thing what my mother could not do the school i was in did. It was Boys Republic in Ca. saved my life. That is my little story thanks for listening.
