"I was obviously struggling with a couple of things on and off the court this year, so it hasn't been easy. But I'm starting to see some psychologists and trying to get on top of my mental health," Kyrgios said.
Kyrgios has worked with psychologists in the past, but says he now feels more comfortable speaking about mental health and being open about the challenges he faces.
