Anxiety can be a normal response to stressful situations. It includes both an emotional component, feelings of fear, worry, dread, or unease, as well as physical symptoms, sweating, increased heart rate, or quick and shallow breathing. When a person’s anxiety begins to interfere with their ability to function from day to day or is incongrous with their circumstances, they may have an anxiety disorder. There are many types of anxiety disorders, including generalized anxiety disorder, panic disorder, social anxiety disorder, illness anxiety disorder, and specific phobias. The good news is that all are very treatable.
