"I felt [I was] being bullied," said Douglas, who won the all-around gold medal as well as team gold in London.
Hawkins told Winfrey that Douglas started asking to move away at age 11 and even discussed leaving the sport at age 14.
"She said, 'I'd rather quit. If I can't move and train and get another coach, I'd rather quit the sport' " Hawkins said.
Douglas said some of the bullying was racial in nature, describing one incident involving the scraping of the bars in the gym. "They're like, 'Why doesn't Gabby do it? She's our slave."
She added: ""I definitely felt isolated. I felt, 'Why am I deserving this? Is it because I'm black?' Those thoughts would go through my mind."
Of course, there were plenty of uplifting moments on the episode as well, including a fun segment with Douglas, her mother, siblings and grandfather.
