My family is breaking apart. How do I sort it?

Call an aunt or grandmother and see if they would let you move in with them. Your mother is putting you in a very bad place and it is not fair of her BUT she doesn't even know how to solve her own problem let alone yours. If you can find someplace until you are 18 and are finished school that would be wonderful .. I really hope you can get out of there. Get an after school job as soon as you are able and save every penny you can for your future. You are learning from this how important it is to pick out your wife, the future mother of your children. Marry someday a girl who is loving and quiet and peaceful.
