As humans, we are familiar with the concepts of anxiety and stress. They are related, but somewhat different in their origins and treatment. Anxiety is generally seen as an unpleasant emotional state, including feelings of uneasiness, apprehension, and distress. Stress, on the other hand, is caused by specific external circumstances such as problems at work, family and financial conditions. How we deal with stress varies with the intensity of our reaction to stressful incidents and our innate or learned coping skills.
