narcissismNarcissism is a mental disorder in which people have an inflated sense of their own importance, a deep need for admiration and are obsessed or infatuated with one’s self to the exclusion of others. They believe that they’re superior to others and have little regard for other people’s feelings in their dominance and ruthless pursuit of self-gratification. But behind this mask of ultra-confidence lies a fragile self-esteem, vulnerable to the slightest criticism.
