I feel as if I’ve just read a full explanation of my own family dynamics. I’ve been working on a story here to attempt to put into words all I’ve dealt with at the hand of a narcissistic sister who was the golden child. Your description of the parental role is spot-on with my parents’ behavior, and your description of the scapegoat decribes my own perspective as an adult: empathetic and determined that I’ll help anyone who’s gone through the same thing.
