When Princess Diana married Prince Charles and became a member of the royal family, many thought she would be content with her new life at the palace. However, Diana reportedly had a devastating experience during her childhood that haunted her as an adult.

Although the Princess of Wales appeared to be in great spirits on her wedding day, she was holding on to a dark secret. According to an astrologer, Diana’s mother, Frances Shand Kydd, is responsible for leaving her daughter emotionally damaged.

When Diana was seven years old, Frances divorced her father, John Spencer, Viscount Althorp. When John won full custody, Frances moved out of the family’s home.

During a chat with the Daily Mail, Debbie Frank explained how Frances left Princess Diana feeling abandoned during her childhood. “Diana had a lot of early pain from her mother leaving her as a child. We talked a lot about that because the damage was so great,” she revealed.

“Even the last time I met her in July before she died, she recounted the story of her mother leaving and packing her dresses into the car.”

Before she became pregnant with Princess Diana, Frances gave birth to a son who died. After Diana was born, she believed she was a disappointment to her parents, who wanted another boy.

“She understood that her mother probably had postnatal depression, and the son who died had a massive bearing,” Frank explained.

“Diana was carrying all her mother’s depression about that, the sense that as a girl, she was a disappointment. Diana was sensitive, and her mother criticized her frequently. There was still the sense of abandonment, compounded by Charles abandoning her,” she added.

Although Diana was sympathetic to her mother’s emotional pain, she struggled to deal with her feelings of rejection. Frances later denied being disappointed about her daughter’s birth. “All I wanted was another baby and a healthy one. I didn’t care if it was a boy or girl,” she previously revealed.

Despite her claims, Princess Diana and Frances had a strained relationship and weren’t on speaking terms when the princess was killed in a car crash in 1997. Frances died in 2004, after a long battle with several illnesses.
