People with Narcissistic Personality Disorders have an inflated sense of their own importance, a strong sense of entitlement, a deep need for admiration, yet a lack of empathy for others.
They use verbal abuse for power and control. Verbal Abuse is often dismissed as insignificant when compared to physical abuse. BUT, the long-term effect of verbal abuse is that you can lose your sense of 'self'. You no longer know who you are. It feels like you've lost your soul.
