Princess Margaret, as the Netflix series “The Crown” frequently shows, drank excessively. Though her father died of lung disease from smoking, she generally smoked more than 60 cigarettes a day. She was frequently depressed. Harry and his wife, Meghan, Duchess of Sussex, a biracial American actress, described feeling depression and anxiety before they walked away from royal life. They now live in Southern California. Harry traces his struggles back to the death of his mother, Princess Diana, in a high-speed car crash in a Paris tunnel in 1997. He compared being a royal to being an animal on display at a zoo.
