Tyson, 47, says he's been lying to everyone that he's been living a clean, sober lifestyle over the past few years.
He admits to being an alcoholic and he's hoping to make a positive change in his life.
"I wanna live my sober life. I don't wanna die. I'm on the verge of dying, because I'm a vicious alcoholic," the former heavyweight boxing champion said on ESPN's Friday Night Fights.
"I'm a bad guy sometimes. I did a lot of bad things, and I want to be forgiven. So in order for me to be forgiven, I hope they can forgive me. I wanna change my life, I wanna live a different life now."
Tyson says he has been a continual substance abuser but he's doing his part to finally become clean.
"I haven't drank or took drugs in six days, and for me that's a miracle," he revealed. "I've been lying to everybody else that think I was sober, but I'm not. This is my sixth day. I'm never gonna use again."
Tyson hopes to make amends for his past transgressions, by saying sorry to those he has hurt.
"Life is short, man. I made amends with everybody," Tyson told ESPN's Todd Grisham. "I never talked to Teddy or made any kind of amends with him or said, 'sorry.' And I just owe that to my sobriety to make amends. And that's just what I want to do with my life. I'm a vicious addict and I'm recovering. And I'm going to die if I don't follow my steps, I'm useless. If I don't do what the book tells me to do I'm going to die and that's just what is going to happen."
Recently, Tyson has been heavily involved in the MMA world, appearing regularly as Dana White's guest at UFC events.
