I know far too much about narcissism. I won’t get into the details of growing up with a narcissistic mother (& grandmother), ending up with a bossy narcissistic sister. But my healing came through Jungian therapy, for a long time. And reading about it from Jungian authors. They get it because of its mythological backgrounds. And if you don’t fully understand the myth of Narcissus, you will never fully grasp its danger to normal people. It’s not catching, though a child raised by a narcissistic parent has to make his/her own journey of healing because of the level of toxicity with which they were raised.
You only mentioned briefly something about romantic relationships — phew! That they can be rough, something like that (I highlighted). They can destroy you because you are their target. I did that and escaped. That was long before therapist intervention.
It’s a good article, Robert. I suggest you read some Jungian articles or the classic “Narcissism and Character Transformation” by Nathan Schwartz-Salant.
