Oct. 6 (UPI) -- Russian-born tennis star Daria Kasatkina will end her season early after reaching a mental and emotional "breaking point," she announced Monday on social media.

"'I'm fine,' words I am sure we have all heard from many women and many different walks of life use, knowing they're not fine, they're far from fine, but they continue, breaking themselves a little more each time," Kasatkina wrote on Instagram and X.

"This is me. 2025 has been my 'I'm fine' year. I've been far from fine for a long time and truth be told, my results and performances show that, the fans aren't stupid, they can see it too."

Kasatkina, 28, sits at No. 19 in the WTA Tour singles rankings. She went 19-22 this season. She lost to No. 60 Sonay Kartal of Great Britain in the Round of 64 of the China Open on Sept. 27 in Beijing.
