This work is the result of an extensive institutional research on the impact of the COVID-19 pandemic on the mental health of Rio de Janeiro city residents. Our general objective is to investigate the impact of this event on the mental health of adolescents, seeking to analyse psychotherapy demands in the face of psychological distress present on the emotional development of young people. As specific objectives, we intend to map and compare the initial complaints of adolescent in psychotherapy at the SPA at PUC-Rio, before and during the pandemic, to investigate the different expressions of psychological distress of these young people, and to analyze the evolution of the demand for help, throughout the psychotherapy process, seeking to reflect on the main conflicts of adolescents in relation to parental figures. Qualitative research was carried out, collecting data from 30 semester reports of psychoanalytical psychotherapeutic treatment, with 23 different adolescents, held at the SPA of PUC-Rio, in the years 2018, 2019, 2020 and 2021. For document analysis, the content analysis method was used in its categorical aspect. Three categories emerged from the analysis: initial complaint: from the symptom to the contact with suffering, family conflicts and frustrations with parental care and grief experiences: multiple losses in adolescence. Such categories are discussed from the literature used in the bibliographic review. As a conclusion of this work, we emphasize that adolescence is a phase of life which young people face a variety of grievances. The psychotherapeutic work is significant for the adolescent to face manifestations of suffering, although it has been observed great difficulty in elaboration.
