Merriam-Webster defines anxiety as “an abnormal and overwhelming sense of apprehension and fear often marked by physiological signs” (anxiety). The physiological signs associated with anxiety include increased pulse rate, tension and sweating. In addition, anxiety is a response to a perceived danger in a person’s mind and not an actual danger. The person also has doubt about his or her ability to cope which causes undue stress. When anxiety is persistent and chronic, it is called anxiety disorder.
