the psychoanalytic treatment of adolescent girls and of young women suffering from severe food disorders, e. g. specifically bulimic behaviours enables one to point out quite a few problematics whose singularity calls forth metapsychological elaboration : the articulation of both masochism and narcissism enables one to stress the predominance of a moral masochism underlying a severe guilt associated to a specific building of seduction fantasies. Indeed, the subject herein holds an active role, which confirms the strong belief of having seducted the father. Such a “ crime ” compels any recourse to self-punishing behaviours throug an attack on the body within a move which sounds highly melancholic.
