Teafruit,your mother exactly sounds like my mother.She never went for help,so it is not diagnosed by a professional. She was abusive ,MEAN sarcastic,bitter,full of rage,unreasonable, violent and constant attention seeker.Such mother's completely destroy their daughters.Whether the daughter's become the replica of such mother's or not,I am not sure.But I am sure of one thing......growing up in such a chaos makes our brains malfunction. Take help of a professional to treat your pain and try to get out from her as soon as possible.
