As a seven-time Olympic medalist and model, Amanda Beard may appear to have it all but the athlete confessed of past eating disorders and cutting herself in an interview with Dr. Phil.

Dr. Phil on Oprah's Revelation About Her Half-Sister

Beard -- whose autobiography, In the Water They Can't See You Cry, will be released Wednesday -- revealed that there were times when she would train on an empty stomach, which led to cramps and severe hunger pains. To relieve her agony, Beard binged on food as soon as practice ended. Following these episodes, Beard felt guilty for her indulgence, which led to purging her meals.

Beard went on to admit to feeling so much anxiety that she used cutting herself as a way to relive stress.
