Cara Delevingne contemplated suicide.
The 'Paper Towns' star admits she put so much pressure on herself when she was at school that she suffered a mental breakdown and considered ending her life.
She said: "I think I pushed myself so far [at school] that I got to the point where I had a mental breakdown. I was completely suicidal, I didn't want to live any more. I thought that I was completely alone.
"I also realised how lucky I was, and what a wonderful family and wonderful friends I had, but that didn't matter. I wanted the world to swallow me up, and nothing seemed better to me than death."
And the 23-year-old model and actress credits her good friend Kate Moss for "picking me up off the floor".
Speaking at the Women In The World conference, she shared: "What happened was I eventually said no, and I eventually took a break, from the advice of Kate Moss, who kind of picked me up off the floor. It's about finding people around you who have your best interests at heart.
"I had a lot of people around me who were just after what I gave them ... not looking after me. So it's about finding people who care about you, and support you. And I've now been able to become a support for other people, as well."
