On the day that he and David Warner were picked up by teams in the forthcoming Global T20 Canada tournament, as part of their plans to return to competitive action while serving 12-month playing bans imposed by Cricket Australia, Smith spoke at Sydney's Knox Grammar School for the Gotcha 4 Life Foundation.
"To be honest, I probably spent four days in tears. I was really struggling mentally and I was really lucky that I had some close friends and family members that I could speak to at all hours of the day," Smith said in audio obtained by the Sydney Morning Herald.
"The people that I had supporting me through that whole time made a huge difference to the head space I am in now."
While Warner took part in the New South Wales squad's 2km time trial to start their pre-season training schedule, Smith is expected to keep training privately before making the trip to Toronto, for a tournament where he will donate his fees to community cricket projects in Canada and Australia.
Warner will turn out for the Winnipeg Hawks in the tournament that runs from June 28 to July 15, while Smith - a marquee player - will play for Toronto Nationals. After this tournament, Warner has committed to playing cricket in Australia's Northern Territory along with Cameron Bancroft, the third player to be banned during the scandal. They will play in Darwin's limited-overs Strike League, with Bancroft committing to playing the entire tournament while Warner will play two games.
The Global T20 Canada will take place at Maple Leaf Cricket Club located in King City, Ontario, a small rural village 25 miles north of downtown Toronto. Apart from Smith and Warner, some other high-profile internationals taking part include Pakistan allrounder Shahid Afridi, Sri Lanka fast bowler Lasith Malinga, and West Indian T20 superstars Chris Gayle, Andre Russell, Sunil Narine, Darren Sammy and Dwayne Bravo.
