Cara Delevingne has opened up about her prolonged fight with depression, saying writing and yoga helped turn her life around.
The model-turned-actress said she had felt "completely suicidal and alone" and wanted "the world to swallow me up" in her school years.
She said part of her recovery was learning how to say no.
Of her frantic modelling career, the 23-year-old said: "I had no concept of saying no to anyone, ever. In life you should always experience things but you should say no. It's more about being in control and not being a puppet.
"Because after a while I just started to get sick and got this horrible thing, psoriasis."
