Diana’s ID: From childhood she suffered from borderline personality disorder, bulimia, and serious depression. Diana's childhood, adolescence, and early adulthood provided sufficient situations and stressors to account for psychodynamic behavioral problems. I think what really triggered
her problem’s was that her mother left her father for another man. Diana was six years old then. Diana and her sisters were caught in a custody battle between their parents that lasted for years. As an adult she lived a regular life. She became a teacher. Lived in a 2-bedroom apartment.
Diana’s Superego:
When Diana was in her twenties, she met Prince Charles's at a weekend party in the country. His mother, Queen Elizabeth, and her advisors were pushing Charles, to get married. Charles had no interest in marriage. It soon became apparent that Diana fit the bill--pretty, charming, well mannered, and well bred. Soon after she became a part of a Royal family. That busts her superego. She was unhappy in her marriage. They tried to hide it from the media, but couldn’t do it. They got a divorce and eventually bringing it to catastrophe.
So my conclusion is that her behavior supports Freud’s theory.
