I have been to prison. Not so in narcissism. The out has long faded into oblivion. And there's no way out. They feel bad, sad, distraught most of the time.
Narcissists are addicts.
They are no different from drug addicts. Narcissists home on potential supplies like cruise missiles with the most poisonous load. They are excellent at imitating emotions, exhibiting the right behaviors and manipulating. There is an abyss between knowing and feeling and between feeling and healing. So, it does not matter what you think - it matters how you feel and behave.
