'Princess Diana had a lonely and isolated life in the Palace,' says royal expert

While on the surface it may have seemed that Diana, Princess of Wales, led a charmed existence, her short time on Earth was never easy.

After enduring a turbulent upbringing, in which her parents’ marriage bitterly broke apart, she fell into a hasty union with the Prince of Wales which eventually left her feeling miserable and alone. “She was the girl who would walk out of Kensington Palace to the cheers of the public, but inside the Palace walls, she had a very lonely and isolated life,” reveals Andrew Morton, who wrote his best-selling biography after he received top-secret tape recordings from Diana.

As her unhappiness intensified, she faced a harrowing battle with depression, bulimia and self-harm – which came to light in Andrew’s book and the controversial 1995 televised Panorama interview with Martin Bashir.

Her deeply personal confessions triggered shockwaves worldwide, but also did much to help topple barriers around mental health.
