Nick Kyrgios reached the semi-finals of his first Grand Slam at Wimbledon on Wednesday
"I never thought I would be in the semi-final of the Grand Slam. I thought the ship was gone, that I might have broken that small window in my career," Kyrgios said.
"I'm very happy that I was able to get out of here with my team and I was able to do well."
He added: "I felt like I was playing in the very back foot.
Garin is a hell of a player. I was lucky with a few break points so I will take them and prepare for my next game."
Kyrgios, who famously defeated Nadal in the tournament as the 144th ranked player eight years ago,
He entered the game in the dark after it emerged he would face an Australian court next month to answer allegations of assault.
A smart, crowd-pleasing shot accompanied by a $ 14,000 fine and a vicious, painful spit on third-party rival Stefanos Tsitsipas.
The 27-year-old was sidelined in Wednesday's first leg of the game as Garin scored his first nine points.
