KAREN WEHRSTEIN – With all the talk of Donald Trump’s mental health status, I’ve decided to do something I’ve put off for a while: write a diary that shows he is a textbook case of Narcissistic Personality Disorder (NPD), and spell out what that means in terms of what to expect from him and how to deal with it. Certainly the term “narcissist†is being applied to him a lot, but most people don’t know the entirety of what that means, psychologically.
