Your mother’s behavior is inexcusable. Period. You may be used to it, and you are asking people how you can fix it by doing the right thing but how will that help? Her behavior is because SHE has a problem, not because you were wrong.
I am so sorry for you, when you are old enough I hope you can find a way to move out and dorm or board somewhere where you can have role models who will teach you skills to help you raise your own family. It may sound extreme, but so sounds the situation. I wish you hatzlacha.
