Abstract. In every sphere of life, whether it is education, academic or personal, adolescents feel lots of obstacles on the way to their goals in life. Sometimes they are able to deal with them rationally but sometimes they deal with them emotionally. If they are incapable of dealing with these obstacles, they become frustrated. To cope with frustration, the adolescents need time to develop their social and emotional skills. This means that they should have flexibility, optimistic thoughts and skills to control impulses. The present study willexamine the reactions of adolescents in situations of frustration and the general level of aggressive tendencies, as well as the presence of a link between reactions of frustration and aggressive behavior. During the period of 2018-2020 we have consulted with 212 adolescents and their parents in our practice. Informed agreement for inclusion in the study of the characteristics and dynamics of reactions in situations of frustration was obtained from the parents of 109 adolescents, who were all male – 57 (52.3%) aged 12-14 years and 52 (47.7%) ) aged 15 -17 years. The results showed that the adolescents are focused on their inner world and believe that the world should be what they want it to be. They lack enough experience to judge and accept opinions that differ from their own. They try to hide the uncertainty in their abilities and skills, relying on protective mechanisms.
