In the community of Casale Monferrato, exposure to asbestos has led to an extremely traumatic situation that has encompassed cancer and death and affected a variety of social and environmental aspects of both individuals and the community. When an entire community is severely traumatized, psychoanalytic group therapy seems to be the most suitable therapeutic setting: it allows for the historization of the event and the creation of multiple narratives of somatopsychic suffering, producing a transformative effect on nonmentalized emotional aggregates. Making reference to clinical material, I will show how the possibility of sharing, with other minds, the meaning of the trauma also brought into the field each participant's vital aspects, possibly not very intense in each individual but consistently present in the functioning of the mind of the group. I will also illustrate how this led to the development of a new and more mature psychic asset, with which painful and deadly experiences connected to the trauma could be faced.
