Martina McBride's new single, 'I'm Gonna Love You Through It,' is another strong and moving song from the powerhouse singer that her fans have really grown to love. The moving ballad about a woman battling cancer was written by Ben Hayslip, Jimmy Yeary and Yeary's wife, Sonya Isaacs.

"This was probably the first song I’ve ever written [about cancer]," Hayslip tells Taste of Country. "Sonya had the idea when she came in that day. Sonya’s mom had breast cancer and fought a hard battle through it. We started on this song, and we actually called Sonya’s mom on the phone and put her on speaker phone. We probably talked to her for a good 45 minutes, just about what she went through and how Sonya’s dad handled it."

"She dropped the phone and burst into tears / The doctor just confirmed her fears / Her husband held it in and held her tight / Cancer don't discriminate or care if you're just 38 / With three kids who need her in their lives / He said, 'I know that you're afraid and I am, too / But you'll never be alone, I promise you,'" McBride sings in the emotional opening verse of the song.

"The song is about a couple [saying] 'We’re going to get through this together,'" notes Hayslip. "It’s not just the woman, but the man, too … 'I’m gonna love you through it.'"

"When you're weak, I'll be strong / When you let go, I'll hold on / When you need to cry, I swear that I'll be there to dry your eyes / When you feel lost and scared to death, like you can't take one more breath / Just take my hand, together we can do this / I'm gonna love you through it," McBride belts in the chorus.

"It’s one of the realest songs that I’ve ever written," says Hayslip. "I was sitting there tearing up listening to her mom talk. I’ve never had anybody in my family go through breast cancer, knock on wood, but just to hear her story ... It was unbelievable. The stuff that she had to go through to stay alive. I think it’s a big song, and I think it’s a real song. Hopefully this song can change lives. Most of the time, we try to write fun, up-tempo, feel-good songs, but this one is actually going to touch a lot of lives I think."
