In this article, the construction of the biographical identity of self-harmer who belongs to the online self-injurers community in Russian social network “Vkontakte” is analyzed. We applied a poststructuralist sociological approach to self-harm, this supposed viewing self-injury as a center of discursive struggles between different social actors and institutions. Our goal was to understand how self-harming person positions herself concerning diverse cultural discourses. We wanted to identify not only the patterns of biographical work but also the place of self-mutilation in the narrative. Before the interview we analyzed the discourse of the online community to which the informant belonged, we based our guide on the literature review and the results of discourse analysis. The sequential and thematic analyses were employed to investigate the interview data. As a result of our analysis, we identified the existence of normalizing and pathologizing discourses in the narrative and the ability of discursive influence to be differently included in the narrative (on the language and logic levels). Furthermore, we came up with methodological suggestions for further studies of the Russian online self-harm communities. The discussion of the biographical structure of self-harmer and the self-injury representations in it could become part of the discussion on the status of online mental health communities that exists among social scientists. This article also helps to illustrate the ability to combine the sociological and psychological optics in the studies of mental health.
