The core problem of the narcissistic personality is an extremely unstable self image. You might show yourself as self assured and superior to others but deep within you might have a strong feeling of inferiority and insecurity. Your feelings of superiority tend to make you feel entitled to admiration and privilege, but as others often do not share your grandiose vision of yourself, you get hurt and disappointed easily. It is hard for you to form relationships at work as well as in your personal life because you tend to focus mostly on your own needs, rights and feelings. At the same time you need other people to reassure you and look up to you.
