Alongside a close-up photo of her with a red face and teary eyes as if crying, Dokic wrote that on April 28 she came close to committing suicide.
“You’ll never forget the day,” she wrote. “It’s all blurry. Everything’s dark.”
“No tone, no picture, nothing that makes sense…just tears, sadness, depression, anxiety and pain.”
The 39-year-old also explained on Instagram how she was experiencing “continuous feelings of sadness and pain” and that getting professional help saved her life.
CNN has contacted Dokic’s representatives regarding her position.
“The past six months have been difficult,” she added. “The crying was going on everywhere.” “From hiding in the bathroom while working to wipe my tears so no one can see them to the unstoppable crying at home within my four walls was unbearable.”
Dokic, who has been a broadcaster for Australian media since retiring in 2014, won six WTA titles and finished fourth in the world rankings.
She reached the semi-finals of Wimbledon in 2000 and the quarter-finals of the French Open and Australian Open in 2002 and 2009 respectively.
In her Instagram post, she said she was “on the way to recovery”.
“Some days are better than others and sometimes I take a step forward and then take back but I’m fighting and I think I can get through that,” Dokic said.
In her autobiography, Unbreakable, she detailed allegations of physical, verbal and mental abuse that she says her father inflicted on her throughout her tennis career. The New York Times reported that he denied at least one allegation of physical abuse of his daughter when she was a teenager.
“I suffered from depression for a very long time, almost 10 years, and I almost committed suicide at one point.”
Dokic, who was born in Croatia before her family fled to Serbia and then to Australia as war broke out in the Balkans, told CNN she shared her experience in the hope that it would “raise awareness of abuse and domestic violence and in sports and also outside of sport.”
At the time, Dokic’s father Damir did not respond to CNN’s request for comment. He told Serbian daily Blic in 2009 that “there is no child who has not been beaten by his parents, like Jelena.”
There was a huge outpouring of support in the comments section of Dokic’s post, including from the tennis community.
“I’m here for you and just a phone call!” Former Australian player Mark Philippoussis wrote, while French star Alize Cornet added: “You can do this Yelena…we love you!”
Dokic ended her post by reminding others who are also struggling to get help, and encouraging them not to feel ashamed.
“I am writing this because I know I am not the only one struggling. Just know that you are not alone.
“I wouldn’t say I’m doing great now, but I’m definitely on the road to recovery.”
I reminded people that it’s OK to feel sad, but you have to keep fighting.
“I love you all and here I am fighting and surviving to live and see another day. I will come back stronger than ever.”
