I don't know where that came from - Dealing with psychological splits
A number of clients tell me how they sometimes experience a part of themselves that takes over and how it is not like them; they don’t feel themselves when this happens. They describe how they become ‘a crazy person’, angry and destructive, clinging and needy or insecure, when they don’t feel that most of the time in their lives. They often can’t understand how they could behave in these ways and feel terribly ashamed of themselves when this happens and the problems it causes in their relationships.
