One of the principal landmarks of individualization seems to be given by discourses around psychological suffering and mental health. A new and profound mutation of the social rule is indicated by the systematic use of such discourses. This article intends to explore how, albeit differently, things today are still social, political and institutional, even if they seem more «personal» than ever: we are not witnessing a weakening but a transformation of the social rule. The notions of psychological suffering and mental health go on an equal footing with the imperative of autonomy. I would like to show that to think of ourselves in terms of autonomy is the core element leading to a redescription of numerous problems in terms of mental health and psychological suffering, adopting a discourse of mass individual vulnerability.
