Russian former tennis player Maria Sharapova says she deleted all social media apps from her phone to protect herself “going crazy” after being banned from the sport in 2016 due to doping violations.

“After the press conference, I deleted all social media apps from my phone to protect myself from being judged and not to go crazy,” the five-time Grand Slam winner said, according to the Punto de Break tennis blog.

“I thought I’ve never worried about what other people thought of me, but after the incident I realized that it was important to me. I was very upset. It was unpleasant to feel so insignificant,” she said.
