The Wikipedia has the following information about this codepoint:
Anguish (from the Latin angustia "distress") is "extreme unhappiness caused by physical or mental suffering." The feeling of anguish is typically preceded by a tragedy or event that has a profound meaning to the being in question. Anguish can be felt physically or mentally (often referred to as emotional distress).
Anguish is also a term used in philosophy, often as a synonym for angst. It is a paramount feature of existentialist philosophy, in which anguish is often understood as the experience of an utterly free being in a world with zero absolutes (existential despair). In the theology of SΓΈren Kierkegaard, it refers to a being with total free will who is in a constant state of spiritual fear in the face of their unlimited freedom.
