“I think I didn’t want to talk about it during the year because I don’t want to give anyone the edge or thinking that I’m not feeling well, but I have been feeling well.
“You learn how to just cope after matches. Some days you wake up and you can’t get out of bed and you just have to know that’s how it is, but other days you live and you’re fine. You don’t even feel like you have it.”
She went on to win the China Open a few months after the diagnosis, and added: “I know there are a lot of people in the world that are fighting with this, and hopefully I can be someone they can look up to and say that if I can do this, then they can too.
