Mike, 25 years old, feels very frustrated. He works in a financial company in New York and is under the high pressure of life. He spends most of his time at work and rarely takes a little time to relax and do what he likes. He seldom goes to entertainment venues and avoids learning about things that have nothing to do with him. When noted that he "may be fired." he had difficulty concentrating on communicating because he was busy worrying about how they would look at him. If he loses his job, maybe people all feel him "loser." He often lost his concentration on interaction, overanxious all the time. Sometimes he would be absent-minded, which only made him uneasy. He also replayed the conversation repeatedly, focusing on what he said maybe looks "stupid."

​

Mike has a social anxiety disorder, which should be the primary treatment goal. When he came home from work after a busy day, he stayed in his home and looked at the pedestrians and vehicles coming and going downstairs. Then keep working busily at home. He wants to join friends but is also afraid to be unable to fit in with their conversation. Since working, he has been isolated from the outside world, refused the invitations to eat or hang out, and ignored the phone when the phone rang. He cares too much about others' attitudes and views, which prompted him to have avoidance behaviors. The fearful attitude and negative ideas keep driving him more and more despair, isolation and tend worthlessness.
