While some people may be quick to throw the word “narcissist” around, it is important to remember that there is a distinction between someone being self-centered and unsympathetic, and someone who has Narcissistic Personality Disorder. Many people may have what doctors call narcissistic characteristics, such as feeling entitled or having a strong sense of self-importance. People who have narcissistic personality disorder may be challenging to deal with.
The first step to determine your dynamic with someone who you think is a narcissist is to know the difference between someone with narcissistic tendencies and someone with Narcissistic Personality Disorder.
