Billie Eilish says her mom helped save her life when she was battling depression and suicidal thoughts, and now the Grammy-nominated artist has taken her experiences and turned them into an opportunity to be there for others going through the same thing.

Speaking with Gayle King for Thursday's segment of "The Gayle King Grammy Special," Eilish explained her mom came to her rescue when she was in a dark place. .

Eilish said her mom, Maggie Baird, recognized that music was something her daughter loved but realized they would have to cut back on her tour schedule and learn to say "No." The young artist also went to therapy and had family support to help her through depression.

"We checked in with her all the time about, 'Do you still want to do this?'" Baird said. "She loved doing the shows. The fans and the shows, that's what kept her going."

The 18-year-old has been open about struggling with depression and has since become a mental health advocate.

She reaches out to fans who may be going through a difficult time and offers words of support.

"I just grab them by the shoulders and I'm like, 'Please take care of yourself and be good to yourself and be nice to yourself … don't take that extra step and hurt yourself further and then you can't take it back," Eilish told King.

Last year, Eilish appeared in a PSA for Seize the Awkward, a public service campaign from the Ad Council, the Jed Foundation (JED) and the American Foundation for Suicide Prevention (AFSP), intended to empower 16- to 24-year-olds to talk about mental health issues with their peers and help their friends in need.

A few months later, the "Everything I Wanted" artist got real about her own mental health in a September cover story for Elle.

“Two years ago, I felt like nothing mattered; every single thing was pointless," she said. "Not just in my life, but everything in the whole world. I was fully clinically depressed. It’s insane to look back and not be anymore."
