Dear Spy,
There is always some "truth" in what they say. That is why it is so confusing.It is like an abusive relationship with a man. There is always that element of truth( as to why they hit you) . They will tell you,"I TOLD you that I don't like chicken( your hair in a pony tail, that color dress,etc). Why did you make it?".
The element of truth makes you doubt your reality. Then, they can keep abusing you. Our" tie in "to them is that our sense of self is weak. We doubt our "truths".
They can "play us" like a violin b/c we do not value and trust ourselves. We need to get "intestinal fortitude"( another digestive reference)
Spy, try to build up your internal sense of value. That will be the best antidote to going in to a "dark place" b/c of your mother's actions. I have you in my prayers Love Ami
