The Japanese star's feelings have been on the roller coaster lately.
From being crocheted during the tournament in Indian Wells to triumphing in Miami.
2-1 in sets against Olympic champion Belinda Bencic took the four-time Grand Slam winner to Saturday's final, where she meets world setter Iga Swiatek.
- When it comes to the match, I'm glad I got through it, says Osaka and admits that her first thought after the match was how she would get her favorite food.
Osaka has been open with her fight against mental illness, which became a public issue after she withdrew from the French Open last year and took a break from tennis.
- If I had not said something during the French Open, I do not think anyone would have known what I was going through, she says.
She says that mental illness is not something new for her.
- People say I'm back, but to be honest I do not think I ever disappeared.
I have always been this player, says Osaka and says that she had a hard time controlling her thoughts even before this match.
- Sometimes I get overwhelmed by my thoughts, in this case it is because I have not been in a final, or really a big tournament, for a long time.
I was very nervous during the warm-up.
