This paper presents an account of the psychoanalytic treatment of pathological mourning in the context of early psychic trauma. I introduce the concept of blank pain, understood as a negative of early trauma, to describe a distinct type of unthinkable anxiety. And I treat pathological mourning as a defence against the unbearable pain of the latter. Clinical observations reveal the extent to which, in a situation where the patient reacts to environmental failure by maintaining a façade (an insincere self), the construction of meaning depends on the use the patient makes of the analytic process and the setting. Considering these observations, I explore the relationship between the structural phenomenon of blank pain and defensive pathological mourning through the therapeutically mutative action of processive interventions and co-enacted scenarios.
