They may cover up in ways that look polar opposite, but each is still driven by neurotic shame. In fact, the most paradoxical aspect of neurotic shame is that it is the core motivator of the superachieved and the underachieved, the Star and the Scapegoat, the 'Righteous' and the wretched, the powerful and the pathetic. Much has been written about co-dependency. All agree that it is about the loss of selfhood. Co-dependency is an condition wherein one has no inner life.
Happiness is on the outside.
Good feelings and self-validation lie on the outside. They can never be generated from within. There is no significant difference in that definition and the way I have described internalized shame. It is my belief that internalized shame is the essence of co-dependency. It seems obvious that some of these types of disorders are related to symptoms of shame.
