The author reviews the main points in Freud's 1917 paper ‘Mourning and Melancholia’ and relates them to the process of both normal and troubled adolescent development. Using clinical examples she illustrates the ways in which the processes Freud describes in melancholia operate in some disturbed adolescents such that instead of mourning the lost objects of their childhood, they become stuck, remaining ambivalently attached to them and incorporating them into their final adult identity and sexual organization.
