Twitter: @Caradelevingne The 23-year-old told followers she never said she was quitting, despite telling The Times last year she's "not doing fashion work anymore." Twitter: @Caradelevingne She added that she doesn't blame the industry, most likely referring to an essay she penned for Motto. Twitter: @Caradelevingne In the essay she wrote: "I found myself surrendering to the industry’s approval process. I felt like I needed validation from everyone. As a result, I lost sight of myself and what it meant to be happy, what it meant to be successful." Delevingne has previously spoken about her struggle with depression at the 2015 Women in the World Summit. Stuart C.

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." Delevingne ended her series of tweets by linking to this picture on her Instagram. instagram.com If you are in a crisis in Australia, see a list of resources here.
