I found another very informative video from Richard Grannon.  Here he talks about the ways C-PTSD, NPD, and BPD inter-relate and can even resemble each other, and why victims of narcissistic abuse can adopt narcissistic traits or even full-blown NPD.

This is definitely a confusing field and sometimes it’s hard to tell the real victims from the real narcissists.   There are a few things here I didn’t know.    Maybe the only people immune from developing narcissism are people who were never traumatized by a narcissist or a borderline — which means you might have to live in a bubble..
