Former world number four Caroline Garcia will not play again this season after being left "exhausted" by anxiety and panic attacks.
The 30-year-old Frenchwoman did not made it past the second round of a Grand Slam event this year.
As well as a shoulder injury, Garcia, who is now 36th in the rankings, says she has been suffering from the mental toll of life on the tennis tour.
"I’m tired of living in a world where my worth is measured by last week’s results, my ranking, or my unforced errors," Garcia wrote on X.
