MUMBAI: Mental illness is far more common than many people think. It impacts at least 40 million adults in the U.S. alone — that’s 18.1% of the population. But it’s also estimated that two-thirds of depression cases in the U.S. are undiagnosed. That’s why it is so helpful for everyone to talk about it, including celebrities.

Take a look at the gallery to see which stars are bravely and boldly dealing with depression.

Adele

Britain’s hottest singing export, Adele, suffered from postpartum depression after having her son Angelo in 2012, and she opened up about her experience in an interview with Vanity Fair. After giving birth, Adele said she was inundated with feelings of inadequacy as a mother. "My knowledge of postpartum — or post-natal, as we call it in England — is that you don't want to be with your child," Adele said. "You're worried you might hurt your child; you're worried you weren't doing a good job."

Miley Cyrus

The singing and swinging Miley Cyrus has been open about her depression. She discussed it in an 2014 interview with Elle. “I went through a time where I was really depressed. Like, I locked myself in my room and my dad had to break my door down," she said.

Cyrus encouraged people who struggle with depression to seek help, both in the form of talk therapy and medication. "And every person can benefit from talking to somebody," she continued. "I'm the most anti-medication person, but some people need medicine, and there was a time where I needed some too."

Chrissy Teigen

Chrissy Teigen's fans love her because she's honest about the day-to-day realities of being a famous and of being a parent. So when she penned an essay for a 2017 issue of Glamour, she wasn't shy about discussing her mental health. When she and her husband, John Legend, were having their first child, Luna, Teigen struggled with both postpartum depression and anxiety.

Teigen returned to work on Lip Sync Battle four months after Luna was born, but she found that everything had changed. She was experiencing constant pain, loss of appetite, irritability and had lost interest in her career. When she wasn't working, she rarely left her house.

Beyoncé

Millions of fans around the world admire Beyoncé for being a strong, confident, sexy and talented singer and businesswoman. But anyone can struggle with mental illness and that includes Queen Bey.

Beyoncé experienced a bout with depression when she was 19, after Destiny's Child broke up in 2006. "I didn't eat. I stayed in my room. I was in a really bad place in life, going through that lonely period: 'Who am I? Who are my friends?' My life changed," she said.
