From global modelling contracts to film roles and even a no expenses spared birthday trip to Mexico with her squad, Cara Delevingne seems to have it all.

But mental health struggles don’t discriminate, proved by Cara’s admission that she battles the demons of depression and anxiety.

In a revealing interview with The Edit, Cara admitted that she first began to experience depression after being teased and bullied in her formative years.

“Teenagers can be very, very cruel,” she said. “I wasn’t into the same things that all my popular friends were. I was a very late developer. I didn’t have boobs or start my period till very late.

“And that whole thing of being called frigid, and being flat-chested… I felt alienated and alone, because I was like: What’s wrong with me? I always wanted people to love me, so I never got angry with them; I turned my anger on to myself.”

The 25-year-old said she fell into a cycle of self-loathing and black moods.

“I hated myself for being depressed, I hated feeling depressed, I hated feeling,” she continued. “I was very good at disassociating from emotion completely.”

Admitting she has experienced suicidal thoughts, she said:

“I didn’t understand what was happening apart from the fact that I didn’t want to be alive anymore.”

The Paper Towns actress acknowledged that it can be hard to believe she could be suffering when her life seems so glamorous and fun from the outside.

“When I tried to talk to people about it, they wouldn’t want to understand. So many of my friends would say: ‘How can you feel like that?’ and, ‘But you’re so lucky,’ and I’d be like: I know, trust me, I know.

“I know I’m the luckiest girl in the world, I understand all of these things, and I wish I could appreciate it. There is just something dark within me I cannot seem to shake.”
