hi xox
thank you for sharing... it will be hard but it will be for the best. although it is hard lesson, you cannot control how much she will drink. you were never able to control it.
remember you did not cause this problem, cannot control or cure it.
by leaving her it is possible she will start reflecting on her own problems and seek help. i hope it turns out that way.
you are very young and your job is to study, get closer to your brother and dad, have fun with your friends.. you are not responsible for an adult's choices and you are doing very well, taking care of yourself.
we are here for you
