Cara Delevingne explains that she still has to learn to speak openly about her emotions.

The 'Valerian - The City of a Thousand Planet' actress said she had major problems disclosing her feelings in her teenage years. So she never asked for help when she was really bad. "It was the biggest lesson I had to learn: that I communicate my emotions correctly," admits the 25-year-old. "I'm still learning how to do it."

The beautiful model reveals to 'ELLE' magazine about her difficult youth: "It felt as if I was completely alone and I could not express myself because I was ashamed of my emotions." That is why the British woman has now declared herself a mission to help other young people: "I want to make sure that children recognize that emotions and vulnerability are important and that they should be talked about. We are alone, but we can do it together. We are all human beings and go through the same things. "

Cara's youth novel 'Mirror, Mirror' will be published in October, which she is very excited about. "I've always had this wonderful connection with teenagers since I started social media," she says. With her book she had the opportunity to be "a voice for teenagers" and to speak openly and honestly about the problems of young people.
