19-year-old boy Xiao Zhang usually cheerful personality, good academic performance, in the eyes of his classmates is an excellent student, in the eyes of his parents is also an obedient child. I do not know how, from a year ago, his personality slowly changed, becoming less talkative, reluctant to communicate with others. At first, his parents didn’t care, thinking it was just due to the pressure of studying. Suddenly, one day, he proposed to his parents that he didn’t want to go to school anymore, which startled them a lot. With all the questions, his parents took him to the psychological counseling clinic at the seventh hospital in the city. One day three years ago, he was chatting with some classmates (both male and female), and as they talked, he suddenly felt his heart beating fast, and it became difficult to spit out words. Afraid of being discovered by his classmates, Zhang hurriedly lowered his head and pretended to organize his clothes. To his credit, the class bell rang and his classmates dispersed at once, and no one noticed his embarrassment. But from then on, he began to be afraid of communicating with his classmates, especially when both male and female students were present, he would feel especially nervous, speak unnaturally, panic, blush and sweat. Nevertheless, if he was alone with his male classmates, a few female classmates, or when interacting with his teachers, he was still largely natural and not too nervous, and his studies did not suffer as a result. It was only a year ago that he found out he liked a female classmate, and he felt especially nervous when communicating with her. Based on Zhang’s condition, I diagnosed him with “social phobia” and recommended that he be hospitalized, considering that his current symptoms had made it impossible for him to attend school normally. After hospitalization, Zhang took anti-anxiety medication to reduce his nervousness and physical discomfort when interacting with others, and also received cognitive-behavioral therapy. Gradually, he became more relaxed and more sure of himself when interacting with others. 1 month later, he returned to class and took the college entrance exam, successfully getting into a university he was more satisfied with. Social phobia is a common disorder whose basic characteristic is an intense fear or anxiety about social situations. When exposed to social situations, individuals are afraid that they will be given negative evaluations, and that they will show blushing, shaking, sweating, or stuttering and be given negative evaluations by others. The fear, anxiety, and avoidance of social situations often significantly interfere with the individual’s normal daily activities, work or study, and interpersonal interactions. In 2013, I conducted a survey in three universities in Hangzhou, China. 1,534 people participated in the survey, and the results showed that 56.3% of people had no anxiety, 28.7% had mild social anxiety, and 15% had moderate to severe social anxiety that needed attention or medical treatment. This shows that social anxiety is not uncommon in our society. If you feel that your social anxiety is affecting your normal life, be sure to seek medical attention early.
