Most people experience feelings of anxiety before an important event such as a big exam, business presentation or first date. Anxiety disorders; however, are illnesses that fill people's lives with overwhelming anxiety and fear that is chronic, unremitting and can grow progressively worse. National Institute of Mental Health provides a detailed booklet that describes the symptoms, causes and treatments of the major anxiety disorders, with information on getting help and coping.
"Social Anxiety," which some people dismiss as "shyness" can be debilitating and limit you from activities you'd like to enjoy or people you'd like to meet. The fear of looking silly or saying something "stupid" can limit us and reduce the quality of our lives.
The University of Buffalo Counseling Services web site has an entire section devoted entirely to Test Anxiety! It also has suggestions for how to arrange your study area most effectively (75 watt bulb is best and on the side of the dominant hand), how to confront your test anxiety head on, how to cope with the feeling of being overwhelmed and some ideas for self-affirming statements (which is healthy "self-talk") to help calm you.
