"I think I pushed myself so far [at school] that I got to the point where I had a mental breakdown," Delevingne admitted. "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."

Cara, 23, subsequently turned to writing and yoga as a means of dealing with her stress.

"I started writing and found yoga," The 'Paper Towns' actress said. "At first I just did it superficially because I wanted to be flexible, but when I first started seeing my tutor I broke through something.

"We were both chanting and I suddenly burst into tears. I looked at him [the tutor] thinking he was a monster - an evil man - for making me cry. But he just laughed.

"See, it wasn't him at all, it was me. Now, we still practice together and I've evolved as a person."
