Hi Zeene,
Why do they do it? are they jealous of the relationship so set out to ruin it?
Usually they are not only jealous of any relationship which draws attention from them, they are jealous of the person themselves.
You came along and now your mother had to pay attention to you rather than others paying attention to and appeasing her. So she's jealous that you even exist.
WHY WOULD N WANT TO TURN MY SISTERS AGAINST ME?
Because in her sick mind you are a threat so she has to pit other people she can influence against you. Your sisters are also potential threats so they are neutralized as well. But there is usually a primary scapegoat who everyone else is encouraged to ostracise.
Why are they called "people"? when they cause so much pain and evilness???????????
Good question. We have to guard against dehumanizing them. They are still, after all, damaged and sick human beings.
But at the same time just what is a human? Does a complete lack of decent human emotions or at last the total suppression of them constitute inhumanity?
Does a complete disregard for the harm they cause disqualify them from consideration as humans? Probably not. I would say maybe they qualify both as particularly sick, but also particularly despicable humans.
Sorry your 'mother' was such a waste.
