Make your peace dear. Be at peace with yourself even if it means cutting off the mother. At some point she'll realize why you don't respond anymore. Or of course you could make peace (for yourself) by going to your mother and telling her all of the things you just put on here, why you feel the way you do towards her and that you don't understand why she acts the way she does. When she argues just walk away. Yes it will hurt her feelings and yes she will get defensive. But after you leave she will think about the conversation and after a time things may heal. If not then at least you tried. Leave it at that and be happy with the life you have chosen knowing that everything you have been through has made you into the person you are today
