The demons Robin Williams could not defeat
Most fans will remember Robin Williams for his bubbly, energetic comedy roles.
He made people laugh with memorable performances in Mork & Mindy and Mrs Doubtfire, but behind the cheerful exterior he admitted there were problems he found it difficult to shrug off.
Williams spoke many times about his battles with alcohol and cocaine and in a 2010 interview with the Guardian's Decca Aitkenhead he talked about suffering from anxiety.
The actor, who was promoting World's Greatest Dad - a film about a father who fakes a suicide note from his dead son - spoke of feeling "alone and afraid" when he started drinking again in 2003 after 20 years sober.
"It's just literally being afraid. And you think, oh, this will ease the fear. And it doesn't," he said.
Asked what he was afraid of, he replied: "Everything. It's just a general all-round arggghhh. It's fearfulness and anxiety."
After three years he went to rehab and continued his recovery by attending weekly AA meetings.
Williams also admitted he had been a workaholic, telling Aitkenhead: "You have this idea that you'd better keep working otherwise people will forget. And that was dangerous. And then you realise, no, actually if you take a break people might be more interested in you."
The actor, who had his aortic valve replaced in 2009, added: "Now, after the heart surgery, I'll take it slow."
At the time of the interview he said he felt happier and was "not afraid to be unhappy", adding: "That's OK too."
Sadly it appears the anxiety and depression which had plagued him had returned prior to his tragic death.
