I relate to your story so much. In my twenties, I have done this drug [cocaine]. I know exactly what you're talking about. It is my life's great big secret. It is such a secret because I realize that the public person that I have become, if the story were ever revealed, the tabloids would exploit it and what a big issue it would be. But I was involved with a man in my twenties who introduced me to [cocaine].... I always felt that the drug itself was not the problem, but that I was addicted to the man. I've often said over the years in my attempt to come out and say it, I have said many times, 'I did things in my twenties I was ashamed of,' 'I've done things I've felt guilty about.' And that is my life's great secret that's been held over my head... I understand the shame and I understand the guilt, I understand the secrecy, I understand all that.
