Emma Stone backs child mental health awareness campaign

Emma Stone has thrown her weight behind a campaign which raises awareness about childhood anxiety.

The La La Land actress always appears poised and composed on the red carpet, but has had an ongoing battle with anxiety for years, and at times in her life she has struggled to feel comfortable leaving her home.

Now, Emma is speaking candidly about her experiences in a video for the Child Mind Institute, in the hope that she can break down some of the stigma surrounding mental illness in young people.

"It has always been something that I've lived with and it flares up in big ways at different times in my life," she says in the clip, according to People. "Sometimes while it's happening, like while I'm in a phase of big turmoil, it feels like it's never gonna end - but it does."

The Oscar winner added that as a child she struggled with separation anxiety and found it difficult to imagine living on her own. But as she's grown and been taught tools by a therapist to help her cope with her overwhelming feelings, the 28-year-old now lives a "pretty normal" and "vibrant" life.

"It's so nice to know in those moments of real intensity that it will shift and it will change and there's a lot I can do to help myself," she added.

The Child Mind Institute is a nonprofit organization that is dedicated to transforming the lives of the estimated 17 million children in the U.S. struggling with mental health and learning disorders.

Emma's video forms part of a larger series being launched by the organization. Other celebrities, including actor Jesse Eisenberg and Olympic swimmer Michael Phelps, will also share their personal experiences to support the campaign.
