In all my time working as a psychologist I’ve only met with 1 person who truly met the diagnostic criteria for narcissistic personality disorder. I ended treatment relatively early, after maybe a month or so, when I recognized the hour was being spent as a time for him to air his grievances and try to prove he was smarter than me. I don’t remember how I put it but was very mindful to avoid causing narcissistic injury (like what we witnessed in the Oval Office yesterday).

He gave me a jar of gourmet mustard as a parting gift.
