Princess Diana 'Contemplated Ending It All'
Charles Spencer recently released a new book about Princess Diana, 'Swan Song: Diana My Sister.'
"It is a sad fact that, in her later years, Diana drove herself more than once to Beachy Head, the highest chalk sea cliff in England, while contemplating ending it all,” Spencer claims in his new book, Swan Song: Diana, My Sister. "Her love for her sons stopped her from going further."
He added that Diana felt "isolated and trapped" in her marriage to then-Prince Charles, who "seemed always to wish she was nearer to 35, in character and outlook."
In his words, she "believed that her husband was sometimes too busy for her, and on other occasions that he was critical."

"We stayed up there [at Balmoral] from August to October. I got terribly, terribly thin," she recalled at the time. "People started commenting: 'Your bones are showing.' By October, I was in a very bad way."
Diana continued, "I was so depressed, and I was trying to cut my wrists with razor blades. It rained and rained and rained. I came down early [to London] to seek treatment, not because I hated Balmoral, but because I was in such a bad way."
