Jennifer Butler Murray left Bill Murray 'Dead and Broken'

Murray said the divorce in May, whose papers included claims by his ex-wife of abuse and that Murray had a marijuana and alcohol addiction, was a very low point in his life.

"That was devastating," Murray said. "That was the worst thing that ever happened to me in my entire life."

A judge ruled that Murray's four children would live with their mother, driving the actor into months of depression.

"I was just dead, just broken," he said of the situation.

"When you're really in love with someone and this happensI never had anything like this happen. It's like your faith in people is destroyed because the person you trusted the most you can no longer trust at allThe person you know isn't there anymore."

Murray also says that after once considering retirement, he has a newfound energy, saying, "I've just come out of a sort of doldrums and I feel like I want to go."

He continued, "I want to work. I want to get going. I want to do a few things at once. I really want to connect with other people that are going that way and 'Let's go' . . . I want to bounce off like a pinball. Like a pinball, I want to bounce off bumpers that are positive. I want to bounce off people that are positive and hope that'll make me more positive and give me momentum."
