Thanks eyesclosed.

You are perfectly correct. I am guessing she was either BP or PBD. I recall being terrified of her changing moods. And yes, it was more about her. If I failed at something she took it as a personal humiliation. In fact, she blamed me for having done so on purpose in order to humiliate her. for example the bullying I endured. Firstly I must have done something to have deserved it but secondly what would people say about her having an unpopular daughter? How humiliating!
