HUNTERSVILLE, N.C. (AP) -- There were days when Tony Stewart couldn't get out of bed. It was a chore to take a shower, to leave his room. The television was on, he would stare at it, and have no idea what he was watching.
He didn't care about racing. He didn't want to talk to anyone, let alone face his family, friends or other drivers. Stewart's grief over the death of Kevin Ward Jr. was overwhelming, and he couldn't find his way out of the fog.
Stewart, one of NASCAR's biggest stars, spent three weeks in seclusion at his Indiana home after the car he was driving struck and killed Ward at a dirt track in upstate New York. He describes those weeks as the darkest of his life.
"I know 100 percent in my heart and in my mind that I did not do anything wrong. This was 100 percent an accident," Stewart told The Associated Press on Thursday in his first interview since a grand jury decided he would not be charged in Ward's death.
On the advice of legal counsel, Stewart would not describe what he remembers about the crash at Canandaigua Motorsports Park.
Ward and Stewart had been racing for position when Ward crashed, exited his vehicle and walked down the dark track in an apparent attempt to confront Stewart. A toxicology report found Ward also had marijuana in his system.
Ward's family has said "the matter is not at rest," and Stewart may still face a civil lawsuit.
Sitting on the couch of his North Carolina home, a sprint car race in Arkansas on mute on the television, Stewart said not being able to talk about what happened is extending his anguish.
"It keeps me from moving forward. It just stays there, hanging over my head," Stewart said.
Ward and Stewart didn't know each other, and Stewart doesn't recall them ever talking. He laments that in the scrutiny that followed - some questioned if Stewart had tried to intimidate Ward for stepping on the track - that the loss of the 20-year-old driver and his promising career fell to the background. He said he can't imagine how the Ward family is feeling.
"I guess the end result is I don't blame them for anything they say," he said.
Understanding how to deal with his grief and getting back on the track was difficult. Stewart has had his share of controversy and drama in his volatile but successful 16-year NASCAR career; none of it prepared him for the emotions he felt following Ward's death.
He said he needed professional help to cope with the situation, and asking for assistance wasn't easy. Stewart, 43, isn't married, has no children and keeps a tight inner circle. He's a solitary figure of sorts, someone who broods and stews alone, and opening himself up for self-examination was a monumental task.
He had no choice.
"You sit there and you wrack your brain, you try to analyze `Why did this happen?'" Stewart said. "I made myself miserable just trying to make sense of it ... I just couldn't function. I've never been in a position where I just couldn't function."
His tumble into depression began almost immediately. Stewart left Canandaigua after the crash and went to Watkins Glen, where he was scheduled to race the next morning. It was roughly 2 a.m. when he got back to his motorhome, and he looks back now and says he was in shock.
But Stewart is a racer through and through, and racers pick themselves up and race. So that's what he told his team he would do.
He wanted to get into his No. 14 Chevrolet that Sunday and go, because that's what he had done his entire life. But when he woke up the next morning, he realized immediately he was in no condition to be in a car, nor did he have the desire to drive.
He did an about-face and pulled out of the race, the first of three he sat out.
"You race hurt, you race sick and that's the way racers have always been," he said. "You say you can go do what you need to do, and then it becomes very clear that you can't."
He watched the closing laps on television at home in Indiana, only because he wanted to see the late-race battle for a berth in NASCAR's playoffs. He watched half of the race he missed in Michigan. Stewart said practices and qualifying sessions didn't interest him, even as the three other cars he co-owns at Stewart-Haas Racing continued with their season without their leader at the track.
It wasn't until Bristol, the third race he missed, that Stewart was interested in watching.
"It just wasn't important to me," he said.
But he had to go back to work eventually, and he had to get out of his house. If he didn't give himself a routine, he would never begin to heal.
So Stewart returned to the track at the end of the August, racing at Atlanta, where he received a rousing ovation from the crowd during driver introductions. It wasn't easy going to the track - it still isn't - and although he's back in his car, his life is far from normal.
At home in North Carolina, Stewart barely steps outside the house. He needed a hairdresser to come to his place just to get a much-needed haircut.
"You are part of something so tragic and so unthinkable, it's hard to face anybody," he said. "It was hard to wrap my arms around this, and it still is. I haven't been a part of society for more than six weeks. You are scared to be around anybody, you are embarrassed to be around anybody because of what happened."
Focus comes whenever he pulls on his helmet and fires up his engine. Though his performance has been horrific by his own standards in his last three races, getting back into the car is a step toward normalcy.
The rest of the time? A day feels like a month. His mind wanders, his emotions get the best of him.
"There hasn't been a day that's gone by that I haven't thought about it. And it will be like that all your life," he said. "You are never going to forget about it. You are never going to not see it happen all over again. It's going to be a part of me forever."
