"I was incredibly confident on stage because that's where I loved to be. But offstage, there was no balance. I was a little shy kid that went onstage. And I always said, cocaine was the drug that made me open up. I could talk to people. But then it became the drug that closed me down. So it started out by making me talk to everyone, and then ended up by me isolating myself alone with it; which is the end of the world, really."
