I share information about my health and life but I don’t want much more sympathy than understanding. That’s my delineation between personal expression and narcissism. Said differently, I use myself as a primary example of situations and interpretations but I don’t let my ego prevent the situation or interpretation from being expressed completely. If I’m misunderstood, I can clarify later. For people that are ego-driven, their desire for outward appearances of perfection prevents their growth.
