Abstract : The character Macabea is presented to the world in Clarice Lispector s book, Hour of the star , as someone against standards and precarized by medical-legal discourse. Here, this literary experience is evoked as an allegory to represent the effect of norms on Mental Health care based on asylum practice. With Macabea, the ideal girl rule delimited borders of your existence and, in this way, we ask how the medical knowledge, specifically the psychiatric / psychological, regulates the existence and forms of survival of persons marked by psychiatric institutionalization? Through the cartographic method, seeking to understand the rationalities involved in the institutionalizing mental health care and the experience of sexuality in this context, accompanying life processes and care (of oneself and the other), the main objective of this work was to investigate the relationship between mental health and sexuality based on the experience of people residing in a therapeutic residency in a Psychiatric Hospital in Santa CatarinaIt was made because of the importance of shows the audible condition of the existence of these people, who undergo processes of forgetfulness and vulnerability. Despite the Psychiatric Reform, there is still a difficulty in dealing with sexuality from the normative and hygienic parameters of health practices. However, what was perceived, like Macabea in her Hour of the Star, was the reiteration of self-care practices within the asylum that shaped an aesthetic of existence capable of proposing folds in the moralizing forces of asylum practice. In addition, this work shows the importance of listening to these stories in order to place them as possible in the space of "externalization" as an alternative to exclusion, criticizing the walls of asylum that follow even metaphorically in mental health practices.
