Robin Williams' actress daughter Zelda has spoken about her father's suicide for the first time, saying "there's no point questioning it".

The Mrs Doubtfire star had been battling depression, anxiety and the early stages of Parkinson's disease when he took his own life at his California home in August last year.

His daughter Zelda Williams, 25, has opened up about the sad loss in her first sit-down interview on US breakfast show.

"There's no point questioning it and no point blaming anyone else for it, and there's no point blaming yourself or the world or whatever the case may be, because it happened, so you have to continue to... live and manage," she says.

Zelda had a tattoo of a hummingbird inked onto her right hand in honour of her father.

"I like hummingbirds. Hummingbirds are fun and flighty and strange.

"It's hard to keep them in one place and dad was a bit like that," she says.

"Keeping a conversation in one moment was impossible with him. It was a bit like trying to put a bag around a storm and hoping that it wouldn't just blow away.

"Sometimes there are going to be days where things are really difficult. And having a reminder that is permanently there is nice."

But it will take some time before she can she can fully come to terms with his death.

"I think a lot of people feel his absence. But for me, especially, it's going to take a lot of work to allow myself to have the sort of fun, happy life that I had," Zelda says.
