Susan Boyle wants the world to know that she isn't crazy. During an interview on the 'Oprah Winfrey Show,' Boyle brushed off all those reports that she was unable to deal with being transformed into an international star. She added that her exhaustion was more the result of working too hard than an inability to cope with her new-found fame.

The 'Britian's Got Talent' contestant revealed the only problem she has faced as a "celebrity" came last year when she was hospitalized for three days. "I hadn't eaten for about a week," she said. "I hadn't slept. The feeling was one of extreme exhaustion. It's a chapter of my life that's over with now."
