Health issues and suicide
Diana had several nervous breakdowns. In 1962, she began working with the Samaritans, an organisation created for the prevention of suicide. In 1963, she died, aged 54, from an overdose of barbiturates. A coroner later concluded that the death was a suicide. She is buried with her parents (who both outlived her) and three of her siblings (Marigold is interred in Kensal Green Cemetery in London) at St Martin's Church, Bladon, near Woodstock, Oxfordshire.

The year 1938 was a bad one for Clementine's health... Again, Winston was too busy to join her. He wrote to her on 19 December... Ten days later Diana gave prematurely and easily to a baby daughter whom she called Edwina. 'The baby is tiny but perfect,' Winston reported, 'and by my latest news, thriving.'
