People who are overly narcissistic commonly feel rejected, humiliated and threatened when criticised. To protect themselves from these dangers, they often react with disdain, rage, and/or defiance to any slight criticism, real or imagined. To avoid such situations, some narcissistic people withdraw socially and may feign modesty or humility.
Though individuals with NPD are often ambitious and capable, the inability to tolerate setbacks, disagreements or criticism, along with lack of empathy, make it difficult for such individuals to work cooperatively with others or to maintain long-term professional achievements. With narcissistic personality disorder, the person's perceived fantastic grandiosity, often coupled with a hypomanic mood, is typically not commensurate with his or her real accomplishments.
The exploitativeness, sense of entitlement, lack of empathy, disregard for others, and constant need for attention inherent in NPD, adversely affects interpersonal relationships.
