"It was all me. I'm the one who did it. I'm the one who acted the way I acted. No one knew what was going on when it was going on," Woods told The Golf Channel in one of two interviews. A second one was aired on ESPN.
"I'm sure if more people would have known in my inner circle, they would have stopped it or tried to put a stop to it. But I kept it all to myself," he said.
Answering questions on camera for the first time since his early morning car crash last November, Woods again provided few details about the crash, his marriage or much of his private life.
"A lot has transpired in my life. A lot of ugly things have happened. ... I've done some pretty bad things in my life," he told ESPN.
But he did admit being nervous about how he'll be received when he returns to golf next month at the Masters.
"It would be nice to hear a couple claps here and there," he told ESPN.
Woods plans to end more than four months of seclusion and play at Augusta National, one of the most tightly controlled environments in golf.
