"The phase in life that I went through was really terrible and it can't be worse. But I've emerged stronger," Yuvraj said on the sidelines of a promotional programme here.
"There's always pressure to come back. Pressure is always there in International cricket. People always expect you to repeat your old performances and records," he added.
Yuvraj, who battled cancer after his Man of the Tournament-winning performance in the 2011 World Cup triumph, said his old form would be back with time.
Keeping in mind next year's World Twenty20 in India, Yuvraj was picked for the three T20Is in Australia at the end of January.

The last time Yuvraj donned Team India colours was in the loss to Sri Lanka in the World Twenty20 final in 2014 where he had a disastrous outing with 11 runs from 21 balls.
But Yuvraj was back to his best in the domestic circuit to send a message to the selectors.
"I'm out of cricket for more than one and half years and it's difficult to motivate yourself to play domestic cricket but that's the only way forward. I've been doing well in domestic cricket," the Punjab batsman said.
Giving credit to his family, friends and 'guruji' (mentor), he said: "The credit goes to my family, my close friends who're always supportive of me. My guruji keeps telling me to keep playing and 'you can come back on top'."
