Performance anxiety is fear and dread about one’s ability to perform specific tasks. People suffering from performance anxiety anticipate failure even before the task begins.
Unlike generalised anxiety disorder, performance anxiety occurs only before specific tasks like interviews, public speech, or stage performances.
Other kinds of anxiety are the panic disorder of sudden intense attack, phobias or fear about certain objects and situations, social anxiety or social phobia, and separation anxiety.
Generalised anxiety disorder (GAD)
Generalised anxiety disorder is constantly worrying about happenings and situations that interfere with day-to-day work. The cause of worry may be finance, family, work, health, future, or anticipation of any disaster. People suffering from GAD find it difficult to get rid of the worry.
