The song was written by Diane Warren (and it's actually titled "How Do I Live?"). What's weird about this song is that it was released by LeAnn Rimes AND Tricia Yearwood at the almost the exact same time (it was Yearwood's version that was included in the film Con-Air). There was no lawsuit (at least none that I heard of), and both versions were nominated in the same category in the same year at the same country music awards show. So Warren must have sold non-exclusive rights to both Rimes and Yearwood, and probably made out like a bandit.
