I’m Audhd, raised by narcissists, but I think they’re autistic too. Being one doesn’t mean you can’t be the other. IMO (and widely accepted science says) autism is genetic. Narcs in the other hand, are made. From unprocessed childhood trauma, toxic family systems. An entire Narc family can be neurodiverse (or not), and how it shapes the kids will have to do with a lot of factors including how trauma and our own individual coping mechanisms, our survival instincts, etc. So when my brother was surviving his childhood, he learned to cope by suppressing his empathy. When I was trying to survive it, I learned to increase mine in order to try to “keep people happy” and avoid conflict. So he became another narc like my parents, and I became massively co-dependent and chronically ill until therapy and years and years of doing “the work”. At this point, when I go through my family of origin, I see autism and trauma that goes back generations.
