What was Serena's traumatic moment?

Serena Williams experienced a significant traumatic moment during the 2018 US Open. The incident involved feelings of perceived injustice when Serena was accused of cheating, which was extraordinarily distressing for her. This accusation triggered an emotional response, as Serena has historically dealt with systemic injustices due to her race. This incident compounded with the pressure of not having won a tournament since giving birth to her child and facing a more in-form opponent, Naomi Osaka, that night. The combination of these pressures and the historical context of her experiences in tennis contributed to a marked emotional outburst during the match 1.
