The text approaches the adolescence to a moment when transformations happen on one person’s relation with its body and love and social ties. At this stage, Freudian theory brings out two big transformations: a new sexual goal and the choice of the sexual object beside a new sexual excitement from what the person cannot escape. That is the moment when, beside the risk of breakdown, there is a tendency to act as a solution for the impasses. This acting comes from the discovery that the body becomes a stranger. The first childhood's familiar body is lost and, in its place, it appears a discomfort towards the body. The impossibility of mourning over the lost body as well as the loss of the ideals and the separation from the parents takes it to a higher rate of death's tempt, many times covered by games and risking acts of the adolescents. Seeing the way in which this body becomes strange and source of anxiety, it allows establishing diagnostic signs. These signs may permit an anticipation of an action that takes to the worst on account of an outcome of a psychosis, many times confused with a common age narcissist crisis.
