The 42-year-old actor said it was hard to overcome the "absolute worst time" of his life, which started during his teenage years when he and his mother were evicted from their home, said the Hollywood Reporter.
Johnson started body building in a bid to get into NFL but he did not get selected. He did make it to the Canadian Football League but was released from the team.
The actor says he slipped into depression after that and even broke up with his girlfriend, Dany Garcia, who he married later.
"I didn't want to do a thing. I didn't want to go anywhere. I was crying constantly. Eventually you reach a point where you are all cried out," he recalls.
Things started looking up for Johnson when he became a hit as WWE star. He soon found an opening in Hollywood
R hosting 'Saturday Night Live' in 2000.
He starred in 'The Mummy Returns' and 'The Scorpion King'. The actor has now been a part of 'Fast and Furious' franchise and next stars in 'Hercules'.
"Now the opportunity is here. The door is wide open and it's as big as a garage," said Johnson.
