Cara Delevingne Left Modeling Behind Because She Wasn't Happy

Cara Delevingne meets up with friend as she arrives back in London, England on Sunday afternoon (March 13).

The 23-year-old actress recently opened up in a new essay about the true reason she left the modeling business – she wasn’t happy.

“It took a while before I had stability in the business,” she wrote. “I worked hard to be accepted by the fashion community in ways beyond my physical appearance. In no time, though, I found myself surrendering to the industry’s approval process. I felt like I needed validation from everyone.”

Cara added, “As a result, I lost sight of myself and what it meant to be happy, what it meant to be successful. I think it all stemmed from a deep-down feeling of wanting people to like me and love me.”
