Narcissists often claim victimhood. It is one of the ploys to gain sympathy and put themselves in the right again, no matter what they've done. They use any and every ploy to be admired or thought of as being right, and having sympathy or even pity can serve their purpose, too. Your post is like the snake who eats its own body: my mother called me a narcissist-how dare she, she is wrong! But I am a monster, I've done horrible things. Now I feel good about myself again, because I, Me, Myself turned my mother's accurate accusation into my own idea. So now its something wonderful I embrace with joy.
