If the narcissist is your parent

If the narcissist is your parent, the same general principles apply. Your worth is only as good to your narc parent as your ability to feed them their need for supply. Children of narcissists idolize their parent and love them, as is natural. The child is completely ill-equipped and emotionally unprepared to cope with this relationship. As a result, the narc child tends to take on the projected shame from their parent, internalizing a deeply embedded sense of inadequacy.
