" Existential nausea comes from feeling trapped. It is an affect state resulting from the feeling that the future has only bad options. Of course every human faces the fact of individual death, and therefore existential nausea must be to a certain extent a universal experience, and something that must be dealt with by one mental strategy or another. Most people appear to learn to ignore it, as if it were some low chronic pain that has to be endured. "
