"I am therefore taking this time to recharge my mental batteries, and to focus on myself away from the game of professional golf. Thank all so much for your continued support. I hope to see everyone soon as I plan to defend my title at the 2018 Indy Women in Tech Championship."
Thompson's post was welcomed by fans on social media who expressed their support for the American golfer.
"Lexi, you do what you gotta do, No matter what us as fans will support you. You got this! Best of luck! I'm praying for you!" one fan wrote.
Thompson captured her ninth career win on the LPGA Tour last September at the Indy Women in Tech Championship, where she plans to make her return to the Tour next month.
