Suicidal behavior among adolescents is now becoming a global problem. Child suicide is a tragedy. Each such situation shows that the fear of life overcomes the fear of death. There are many reasons for suicide among adolescents, and one of the reasons that teachers, psychologists, parents do not pay special attention to is the adolescent's feeling of loneliness.

The authors of the article point out that one of the reasons for suicide among adolescents may be loneliness. At this age, they really need support, understanding of others (especially peers).

The aim of the study is to prove that the cause of suicide among adolescents may be loneliness, the importance of studying and preventing the feeling of loneliness in adolescents.

In an empirical study of the peculiarities of loneliness in adolescence, the authors used the method "Diagnostics of the level of subjective feeling of loneliness" by D. Russell and M. Ferguson, and also conducted a thorough analysis of the research results.

Along with this survey, the authors provide a number of questions to identify the causes of loneliness among students, to help those who feel lonely. As a result of such studies, the authors found that most adolescents experience loneliness to some extent and that this feeling has a certain positive or negative impact on each of them.

The scientific novelty of the study lies in the fact that school psychologists, teachers and class teachers are offered an effective methodology and questionnaires for the study and prevention of feelings of loneliness in adolescents.

In adolescence, the state of loneliness is very pronounced. This condition may be associated with an increase in the social need inherent in this age. Ambiguity, spiritual isolation, melancholy, the need for communication, the closeness of people-all this leads to a painful state and stress. And untimely prevention of this problem can lead to serious, irreparable consequences.
