There is only a certain level or amount of empathy or understanding a person can feel for someone else because no matter what, no one can possibly know exactly what it feels like to be someone else. Do you ever wish someone could crawl into your skin and actually experience what you are physically or emotionally feeling? It could be good or bad feelings, but just to have someone else sense what you sense would probably be the closest to the opposite of loneliness a person could really reach.
