From Unofficial Handbook of the Virtue Universe
Social anxiety is a term used to describe an experience of anxiety (emotional discomfort, fear, apprehension or worry) regarding social situations and being evaluated by other people. It occurs early in childhood as a normal part of social functioning. People vary in how often they experience social anxiety or in which kinds of situations. It can be related to shyness or other emotional or temperamental factors, but its exact nature is still the subject of research and theory. Extreme social anxiety can be disabling and may be diagnosed as social anxiety disorder (social phobia).
