Kate Moss had a nervous breakdown when she was "17 or 18" because she was so stressed about work.
The British supermodel was discovered when she was 14 and quickly booked jobs with high-end labels. In 1992 she shot a campaign for Calvin Klein with Mark Wahlberg, in which they were both topless and she was snuggling up to the male star.
Although the images are what propelled her to superstardom, Kate regrets being involved.
"I had a nervous breakdown when I was 17 or 18, when I had to go and work with Marky Mark and [photographer] Herb Ritts," she tells the new issue of Vanity Fair magazine. "It didn't feel like me at all. I felt really bad about straddling this buff guy. I didn't like it. I couldn't get out of bed for two weeks."
In another early shoot, Kate bared her chest for photographer Corinne Day. She hated having her breasts on display and wishes the incident had never happened.
The 38-year-old felt pressured to take part in the risqué shoot.
"I hated my boobs more than anything as a teenager. I'd do anything not to take my top off. But they were like, 'If you don't do it, then we're not going to book you again,'" she recalled.
"So I'd lock myself in the toilet and cry and then come out and do it. I never felt very comfortable about it... That picture of me running down the beach - I'll never forget doing that, because I made the hairdresser, who was the only man on the shoot, turn his back."
Although she is proud of her career, Kate has struggled with her job a great deal. She admits feeling "a massive pressure" to succeed and claims she has never been looked after "mentally".
Kate's private life has hit the headlines as much as her professional one over the years. Although she is now married to The Kills rocker Jamie Hince, she has reflects on another relationship in the interview.
Between 1994 and 1998 she dated actor Johnny Depp and their split was one of the hardest things she's ever had to go through.
"There's nobody that's ever really been able to take care of me. Johnny did for a bit," she said. "That's what I missed when I left. I really lost that gauge of somebody I could trust. Nightmare. Years and years of crying. Oh, the tears!"
