Canadian singer Chantal Kreviazuk has been releasing music for more than 15 years. She's also written songs for superstars like Kelly Clarkson, Shakira, Pitbull and Avril Lavigne.

It sure sounds like a charmed life. But the darker, more difficult moments are what inspired her latest single, "I Will Be," which touches on issues like depression and suicide.

"I think that I've done a lot of traveling around the world, which gave me access to life experiences and people's stories," Kreviazuk says in a recent interview with Headlines & Global News. "I know what my own personal struggles in my family were. I can deduce that life is harsh, life is a struggle. I think that being a teenager is really, really hard. I think there's been a shift in the very basis of how we go through society, which creates this idea that we're not good enough."

With the song not only tackling such serious themes, but also hoping to offer some solace to those who might be struggling, the singer/songwriter released the song in partnership with Kids Help Phone, Canada's only toll-free, 24-hour, bilingual and anonymous phone counseling and web counseling referral service for children and youth. She also released a video for the song, which was directed by Thomas Cobb, who has done work for "Homeland," "Orange Is The New Black" and a long list of other high-profile clients. You can view the video for "I Will Be" below.

Working with Kids Help Phone was an easy decision for Kreviazuk to make. For starters, her husband, Our Lady Peace lead singer Raine Maida, had done work with the organization in the past, she explains.

"Also, I loved that his organization is so well affiliated throughout the world," she says. "I see my mail every day. I may not have as many fans as Katy Perry, but I have a pool of fans. I think, ultimately, here's a phone number, and you can call and this anonymous person will help you and won't have a bias about you, just that sort of love on the other end of the phone. My mom worked on a phone line when I was a kid, and I really respected that."

The reaction to the song, Kreviazuk says, has been nothing short of overwhelmingly positive.

"I don't want to sound like a jerk, but frankly, I've never had this type of reaction. When I was on Sony - I don't have that kind of support anymore - but what I'm seeing with this song, the reaction is sort of the most potent, and that's why I want it to find its home," she says, comparing the experience to that of her first four studio albums, which were released by major record companies. "I want it to arrive in a place where it will continue to grow, because I'm seeing the impact that it's having."

Kreviazuk is a musical chameleon, which could explain how she's arrived at working with such a diverse roster of artists over the years. Who else could collaborate with, say, Josh Groban, then sing with hip-hop star Kendrick Lamar on "Saturday Night Live?" (She accomplished the latter feat last November).

"I love the Lori McKenna in me," she says, mentioning the singer/songwriter who has worked with A-listers like Mandy Moore and had her songs covered by country superstar Faith Hill. "I love the Rickie Lee Jones in me. I love the PJ Harvey in me. They're all in there. I'm really quite blown away by people who just get 'their sound.' I don't know it I really have that."

One musical act that was not on her radar before she met her husband was his band, Our Lady Peace, the long-running Canadian alternative/hard rock band which has sold millions of albums and won four Juno Awards (the Canadian equivalent of The Grammys) and 10 MuchMusic Video Awards, more than any other artist.

"I never heard of Our Lady Peace when I met Raine," Kreviazuk says. "I was from Winnipeg and, we had two stations, and I listened to the one that didn't play Our Lady Peace."

She shares that they met "at a Pearl Jam concert 20 years ago this September, and we've been together ever since."

Husband and wife have worked together, both as writers and performers, and while she says "we love every drop of time we get together," some professional space helps, because "the more we work apart, the easier it is to work together."

Next up for the songstress? A string of dates in her home country, kicking off April 15. And, of course, penning more songs.

"Always writing, writing, writing," she says. "And you never know what's next if you don't show up."
