We generally think of anxiety as referring to an emotional state such as apprehension, doubt, boredom, mental conflict, shyness, feelings of unreality, fear or even panic. Anxiety may also refer to cognitive deficits, such as confusion, difficulty concentrating, worry, and intrusive, disturbing or negative thoughts.
Anxiety is a part of what it means to be human.
Without anxiety, little would be accomplished. The performance of students, entertainers, athletes, poets, artists, and businessmen would suffer. Anxiety is important to creativity, intelligence, and to survival itself. It is when our response to anxiety becomes unproductive or interferes significantly with normal routine that it becomes important to seek professional help. Without professional help it can become worse and lead to other physical or emotional problems.
