Many actors have come out and spoken about their mental health. It takes a lot of courage to be vulnerable about your weaknesses in front of the entire world especially when you're a public figure. Here are a few of the celebrities who battled depression:

Owen Wilson

His 2007 suicide attempt devastated his friends, family, and fans. Though Owen Wilson's screen persona was that of a loopy, lovable surfer dude, offscreen he was a complex man who, as People reported at the time, has dealt with addiction issues and relationship problems, notably his then breakup with actor Kate Hudson.

Heath ledger

Everyone's favourite "Joker" tragic death in January 2008 will likely never be known: The troubled actor, 28, accidentally overdosed on sleeping pills, painkillers, and anxiety drugs not long after revealing to the New York Times that he'd been suffering from insomnia.

Demi lovato

The former Disney star underwent a three-month-long residential treatment for anorexia, bulimia, and cutting.

"I never found out until I went into treatment that I was bipolar," Lovato told People magazine in 2011. Bipolar disorder, AKA manic-depressive illness, is a brain disorder that causes unusual shifts in energy, mood, and activity levels. It can also interfere with your daily ability to function, according to the National Institute for Mental Health.

Gwyneth Paltrow

"I felt like a zombie," Paltrow told Good Housekeeping in February 2011. "I couldn't access my emotions." Still, she didn't suspect postpartum depression until her husband brought up the idea. "I thought postpartum depression meant you were sobbing every single day and incapable of looking after a child," she said. "But there are different shades and depths of it."

Lady gaga

"I've suffered through depression and anxiety my entire life," she said. "I just want these kids to know that … this modern thing, where everyone is feeling shallow and less connected? That's not human," she told the magazine.

Because of Gaga's own struggles with depression and feelings of isolation, her mission is to help young people facing similar emotional struggles.

The Rock

"I found that, with depression, one of the most important things you could realize is that you're not alone," Johnson said during an episode of Oprah's Master Class on OWN network. "You're not the first to go through it; you're not going to be the last to go through it … I wish I had someone at that time who could just pull me aside and [say], ‘Hey, it's gonna be okay. It'll be okay.' So I wish I knew that."

Deepika padukone

Deepika  spoke out her battle with depression with NDTV.

"It was all downhill from there. I felt a strange emptiness in my stomach."

At first she thought it was stress, and so she tried to distract herself by keeping herself busy with work and an active social life. However, the recurrent negative feelings did not subside: "My breath was shallow. I suffered from a lack of concentration and broke down.
