The goal of the study determined our objectives: to determine the theoretical approaches to the substantiation of the phenomenon of “cyberbullying”; to identify methods and means of assistance to a teenager who has become a victim of cyberbullying at the physiological, psychological and medical level; to describe the activities of a specialist to provide assistance and follow-up for a teenager who has become a victim of cyberbullying.

Materials:
In solving these tasks, the following research methods were used: system analysis and synthesis of international and domestic literature on the research problem; systematization of facts; the analysis of regulations; psychophysiological diagnostics (tеpping-test, kopping-test, Dot cancellation test), psychological research methods (survey in the form of questioning, testing).

Results:
We can draw a conclusion about the causal interdependence of psychological, physiological and clinical and the consequences of cyberbullying for teenagers. Most teenagers who were victims of cyberbullying have a high and medium level of anxiety (which indicates their inherent increased anxiety, which may be accompanied by depression, isolation, unwillingness to maintain existing social contacts and make new ones); a decrease in activity and, as a result, a decrease in school performance; a high level of frustration (which is accompanied by such negative emotions as disappointment, irritation, a teenager has a general sense of wreck); high and medium level of constriction (teenagers with a high level of constriction have significant difficulties in the process of adaptation, which significantly affects the social side of their lives and significantly affects the resolution of emerging problems).

Conclusions:
When providing assistance to teenagers clinical psychologist need to rely on the following principles: systemic; subject-subjectivity, or communication; adaptation and endurance; safety and reliability. These principles will work successfully if the following individual and group methods of psychotherapy are used: creating a new cognitive model of life activity; affective reassessment of traumatic experience; restoration of a sense of self-esteem and the ability to exist in the world; colloquial psychotherapy (logotherapy, which involves the coincidence of verbal argumentation and the internal state of a teenager, leading to self-realization, when a teenager focuses on personal experiences, thoughts, feelings, desires); game therapy, art therapy, music therapy (through the perception of music), vocal therapy (through singing); kinesitherapy and psychodrama.
