I believe that Susan’s behavior is not normal and she does have an anxiety disorder because she is meticulously rehearsing her material repeatedly. It’s normal to have minor fears and anxiety over public speaking; however, when the fear or anxiety is too cumbersome and consumes a person’s life taking them away from their normal routine; which is when the condition effects a person’s behavior or ability to cope with everyday stresses. The fear of public speaking would be associated with a social anxiety because it involves a fear of being scrutinized in a public setting.
