The most talented woman I have encountered suffered from such low self-esteem that she couldn’t bear to look at herself in the mirror. Still, she always presented a glamorous facade to the world, successfully hiding the fact that she had been bulimic since adolescence. That wasn’t her only addiction, however. Over the years she also used sex, drugs, alcohol and even gambling to numb her feelings. It didn’t work, or perhaps it worked too well, since she died in her forties. A body can only take so much abuse before it packs up.
Her name was Georgiana, Duchess of Devonshire; she was the subject of my first book. Subsequently, a film was made about her, starring Keira Knightley and Ralph Fiennes. The film makers focused on her tangled love life rather than her troubled childhood. I guess a story about a mixed-up girl whose emotional struggles become a lifelong burden is all too familiar.
