According to the National Institute of Health, social anxiety disorder is a common type of anxiety disorder. A person with social anxiety disorder feels symptoms of anxiety or fear in certain or all social situations, such as meeting new people, dating, being on a job interview, answering a question in class, or having to talk to a cashier in a store. Doing everyday things in front of people—such as eating or drinking in front of others or using a public restroom—also causes anxiety or fear. The person is afraid that he or she will be humiliated, judged, and rejected.
The fear that people with social anxiety disorder have in social situations is so strong that they feel it is beyond their ability to control. As a result, it gets in the way of going to work, attending school, or doing everyday things. People with social anxiety disorder may worry about these and other things for weeks before they happen. Sometimes, they end up staying away from places or events where they think they might have to do something that will embarrass them.
Some people with the disorder do not have anxiety in social situations but have performance anxiety instead. They feel physical symptoms of anxiety in situations such as giving a speech, playing a sports game, or dancing or playing a musical instrument on stage.
Social anxiety disorder usually starts during youth in people who are extremely shy. Social anxiety disorder is not uncommon; research suggests that about 7 percent of Americans are affected. Without treatment, social anxiety disorder can last for many years or a lifetime and prevent a person from reaching his or her full potential.
