The supermodel, who is infamous for her partying and fierce temper, has said that her hectic lifestyle during her fashion career made her dislike herself.
She told In Touch magazine: "To be honest, there were times I thought I wouldn't survive. The time between 1998 and 2005 was especially bad.
"During that time I avoided looking in the mirror, because I didn't like the person who was looking back at me. So I had to find out what I wanted and what I didn't want.
"The thing is, as a model you're used to being on the go, so just the thought of sitting down and thinking about something drives you crazy."
She added: "I used to have a lot of problems. Amongst others I drank too much so I joined Alcoholics Anonymous to get and stay sober.
"I've grown up. I've stopped driving myself to exhaustion. I want to lead a calm life. I'm done with partying. When you get older things that seemed important to you when you were 20 suddenly lose significance."
