@Walter1964 Not a curse; but it's lonely, and isolating. If one were to define "madness" while removing the social stigma from the term, it would probably be like "being unable to agree on the basic shape and contours of reality, with most of the people around you."
When you know the actual history of the West/Pig Empire but everyone around you is intent on maintaining polite fictions, it has a way of making it very hard to relate to other people in human ways without creating dissonance.
