Being in the public eye means celebrities may hide mental health issues, a psychiatrist told Good Morning Britain.
"We like to be seen as healthy people," Dr Claudia Bernat, a Consultant Psychiatrist at The Priory Hospital said.
Dr Bernat, who specialises in depression and anxiety, was speaking after it was confirmed Robin Williams took his own life.
Her message to anyone suffering from depression is that "it is a treatable illness...the most important thing is to have hope and to engage with the mental health professionals."
Robin Williams' daughter has left social media after receiving abusive messages in the wake of her father's death.
Radio station talkSPORT has apologised after presenter Alan Brazil said he lacked sympathy for actor Robin Williams, who took his own life.
He played a wide range of roles but Robin Williams captured the hearts of millions with his performances.
