I agree with Phoenix about contacting a local al-anon group. You can't save your mother unless she wants to be saved, and it sounds like she's not interested. So stop antagonizing her by forcing your good will on her. You are best off trying to save yourself by planning to be independent as soon as you are able. Try and obtain some skills and experience that will make you employable. You will probably have to work and go to college at the same time, so you want to plan for that. Is there another family or adult you like who might take you in. What's the situation with your grandmother? You mention you have a sister, still in diapers, who is her caretaker? How old is your other sister?
