That… sounds like a working theory. Iirc what I’ve heard of you say of various previous generation relatives, that relationships are/were strained and dysfunctional, I would definitely consider the developmental aspects of trauma as a factor, at minimum. (But I see PTSD everywhere.)

CW: trauma I'm a survivor of CSA by a parent, psychological/emotional/mental abuse by a parent, DV, SA, and an extremely dysfunctional/abusive family that I have no contact with anymore. I'd honestly be surprised if CPTSD *wasn't* doing a lot of lifting there. I really need a therapist.
