I'm starting to suspect that a narcissist is a neurodiverse person who hasn't processed their trauma well and has risen to some position of power and authority over others. My grandma fits that bill. Meh, both grandmas were manipulative. But then they entered survival mode early, lived through WWII during their late teens and early twenties ... fewer chances to develop a self-reflected personality probably? My ex spouse (different nationality and culture from me, of course) is narcissistic as well. Throw enough repression, religious and/or political, into the neurodiverse mix and these figures emerge I guess.

I embrace the voices in my head. I've never been overwhelmed by them to the point of coming close to schizophrenia, but it was never difficult to have whole conversations in my head. I used to interpret them as different parts of myself, these days I'm actually seeing it as a conversation with my non-human surroundings and even ancestors like the above-mentioned grandmas, but I'm keeping an open mind around it all. But I'd definitely tell 'fuck off' to anyone who'd try to tell me I shouldn't be doing that in my own head.
