Adolescence is considered a specific stage of human beings, well distinct from childhood and adulthood. Not a middle way, but a condition in itself, with specific characteristics, anguishes, and defense modalities. After a brief introduction on the hypothesis developed by psychoanalyst Armando B. Ferrari in The Eclipse of the Body, who considers the body as a unique object of the mind, which is produced by the body itself, Adolescence is described as one of the first moments in which the body emerges from the eclipse. Short clinical vignettes show anxieties and defenses, and focus on the use made at this age of resources such as literature, poetry, movies, the imaginary world, social networks, and the peer group. Special attention is paid to depressive tendencies that can manifest themselves at this delicate stage, and are defined as Proto-depression. In conclusion, technical aspects specific to this age are described.
