Manuel finished ninth in the semifinals and was only 0.02 seconds from a final place.

At an emotional press conference afterwards, the 24-year-old said that in March she was diagnosed with overtraining.

Something that has been shown through lack of sleep, depression and sore muscles.

- During that time I was definitely depressed.

I isolated myself from my family.

I had a hard time eating and I think the only way to get out of it was to talk to my loved ones and sports psychologists, she says according to ESPN.

At the Olympics in Rio 2016, the American shared the gold in the 100 meter freestyle with Canadian Penny Oleksiak after swimming in the finish at the same time.

Sarah Sjöström was third.
