This paper aims to explore some theoretical and methodological tools for addressing adolescent and youth subjectivities in contexts of rights violations. The theoretical perspective is nourished by the interdisciplinary dialog between psychoanalysis and contributions from philosophy and the social field. The life story of a young woman from a low-income sector, whose biographical experience was marked by precariousness and violence, was analyzed in a detailed and holistic manner. Such analysis explored the twists and turns of existence, transformations in their identity development, the effects of trauma, and the possibilities of building a future. [ABSTRACT FROM AUTHOR]
