Diagnosing Narcissistic Personality Disorder from afar is wrong. Isn’t it? After all, you are not a mental health clinician, and you never gave the alleged narcissist a battery of tests. It is none of your business. The narcissist will seek help if s/he needs it. Won’t s/he? But wait a minute… why would the narcissist seek help?
Narcissists are not known to acknowledge that they have a problem, and they rarely seek help from a professional.
