Lauren Alaina has experienced a lot in her 19 years. The songstress was the runner-up in Season 10 of 'American Idol,' released her debut album, 'Wildflower,' which landed in the Top 5, and toured with both Sugarland and Jason Aldean.

But while the young singer's career was exploding, she was dealing with a private pain in her family. Her father was fighting, and sometimes losing, his battle with alcoholism. It was a chapter in her life she didn't feel comfortable opening up about, until now.

Alaina poured out her experience of having her father fight the addiction in her new song, 'Same Day, Different Bottle.' The performance above was captured at the CMT Next Women of Country brunch on Monday (Nov. 4). Alaina hopes to record the song for her upcoming sophomore album.

"That song was like therapy for me," she tells Yahoo! Music. "It’s not easy growing up in a household with something like that. I love my dad -- he’s one of my favorite people in the world -- and he’s a great person. He just struggled with alcohol, and he’s overcoming it right now, so I’m really proud of him."

The Georgia native, who co-wrote the song with Caitlyn Smith and Dan Couch, says the song was important for her, whether or not it is ever released as a single.

Though writing the song was therapeutic, Alaina wasn't sure she wanted to even bring it up to her co-writers at first. "Because I never, ever even talked about my dad drinking -- ever -- to anyone," she shares. "Some of my best friends that I grew up with didn’t know; he went to work every day."

Her father recently completed a stint in rehab, earning high praise from his daughter. "Today is a new beginning for him," she boasts. "It’s gonna be a battle for the rest of his life, but I’m going to be right there with him, and pray that every day he doesn’t want to drink it up and touch a bottle. I hope it’s no longer the same day, different bottle. Different day, no bottle!"

As for her relationship with her father, who she has yet to see since he got out of rehab, she says 'Same Day, Different Bottle' has already opened up their communication.

"In a weird way, I think it helped my dad and helped me," she notes. "It’s a sticky situation to talk about, but so many people are affected by it. It’s my situation and there’s nothing I can do about it, except pray that he stays sober and continues the fight every day. I wrote the song while he was in recovery, about how I felt for so long."

The song has already been affecting people, but perhaps none quite as much as her father.  "I played him the song, and he loved it," she recalls. "It made him cry."
