Welcome to the forum, elanlaur.
So sorry you experienced this with your father.
I was in an emotionally incestuous relationship with my mother... I experienced what is called "parentification" as a child and, like you, grew up fast... yet, in my case, remained somewhat regressed in other ways.
I also experienced "triangulation" with my mother and grandmother (my mother's mother) which has the dynamic of victim, abuser, rescuer.
As the rescuer, I still find to this day that my instinct is to help someone else before helping myself... do you have that, as well.
I hope you find these forums to be as helpful as I do. And I wish you the best on your healing journey...
