“I feel like in a way I’m starting over, with everything,” Twain, 44, told Winfrey in an interview at an event in New York on Thursday. “This is a very personal experience that I think is important to share. This is an experience of recovery. I was in a very deep, dark slump, and I needed to find a way to get myself out of it. I had to force myself back out into life, back out into experiencing things.”
Twain’s marriage of 14 years to Robert “Mutt” Lange collapsed in May 2008 due to Lange’s relationship with Twain’s longtime friend and assistant, Marie-Anne Thiébaud. In the months that followed, Twain said, there were times when she had no passion or interest in anything.
“There were moments when I really just thought, I don’t need anything and I don’t need anyone,” she said. “I just want to go away and disappear. So, that was a bad slump.”
