Vladimir, 25 years old, works as a teacher at a university, has experienced constant social anxiety since adolescence, was embarrassed to communicate with others, and also periodically experienced signs of irritable bowel syndrome. Manifestations of social anxiety began to intensify with the onset of professional activity, especially during lecturing. Vladimir turned to a psychologist for help at the age of 24, after he stopped taking lectures at the university, informing the management that he had problems with his throat. The fear of speaking to a “critical” audience became his main problem and he spent most of his time worrying about how to avoid the anxiety of showing his weakness. He considered himself incompetent and was afraid that the audience would understand this.

The psychologist’s main interventions were related to the relationship between past life events and the current situation; this gave Vladimir a certain understanding of why he behaves this way, but his behavior and feelings did not change. During our consultation, Vladimir’s additional beliefs were revealed that it turns out that during the lecture he is constantly monitors his voice timbre and breathing in order to “sound more convincing.” In order to test his beliefs, he began to record his voice during a lecture and then listened to it. These behavioral experiments served to understand Vladimir that his fears were fundamentally wrong, and his conviction in his “weakness” began to gradually decrease. During subsequent psychotherapy, Vladimir began to realize that lecturing him did not have any catastrophic consequences; he gradually changed his assessment of himself and those around him, although he still experiences certain doubts about himself, but they are no longer so fatal...
