Well, anger issues will do it. I had anger and self-esteem issues as a result of being belittled and put down as a child. My husband had anger issues, because his parents died when he was young; and when you're that young you view it as abandonment. People in this situation will do one of two things. They will either try to draw people to them that will continue the control and abuse, because they feel that is what they deserve; or they will "mirror", cause other people to feel the way they do by treating them in such a manner. It sounds like your mother "mirrors". In her mind, she feels that it is only fair for others to feel the way she does.
