The chapter aims to explore the construct of mental health in a psychoanalytic perspective with a psychosocial approach. In particular, the chapter studies mental health by analysing traces to detect social mandate characterizing different mental health agencies. The highlighted hypothesis could be interpreted as that social mandate is a clue of local cultures about mental health, which determine fantasies about mental health issues, grounding on symbolizations shared by professionals, users, and community. The chapter introduces three clinical experiences of interventions, carried out in different contexts: a public mental health service, a public middle school, a psychoanalytic private office. All the presented experiences concern mental health field, even though they are characterized by different features in terms of subjects, methods, professionals, users, and organizations involved. The chapter explores those differences in order to focus on transversal issues.
