CHICAGO -- Suzy Favor Hamilton didn't know she had a mental disorder.
She was the master of the 1,500-meter, a winner of nine NCAA championships, and a well-renowned U.S. Olympic athlete in 1992, 1996, and 2000.
By 2011, however, Favor Hamilton started going down a dangerous path of risky behavior stemming from her inability to cope with her Bipolar Disorder.
Now a 47-year-old book author of her autobiography, "Fast Girl: A Life Spent Running from Madness," the former Olympian has opened up about how her struggle with mental illness led her to six months of "sexual exploration" as a high priced escort in Las Vegas.
