No, it is not easy. Living with someone who excessively values themselves and devalues others can be very difficult, especially if you are the victim of this behaviour. Victims may feel belittled and powerless, constantly second-guessed and criticised. The experience can be incredibly stressful and debilitating.
Narcissists often operate under the false belief that they are special, supremely talented and deserving of adoration. Consequently, they find it hard to understand why their victims would find their behaviour abrasive or intolerable. In fact, many narcissists actually see themselves as being treated poorly by their victims – purely because the victims don't share in their inflated self-perception!
Victims of narcissistic abuse typically suffer from low self esteem and feelings of inferiority. They may also develop paranoia and other mental health problems as a result of being targeted for long term exploitation.
