ABCNow that she's 30, LeAnn Rimes is taking stock of her life.
The country star sat down with Katie Couric for an interview on a special edition of tonight's 20/20 titled "All Access Nashville," and in it, she talked candidly about seeking treatment for stress and anxiety and her tumultuous relationship with husband Eddie Cibrian.
Rimes—who voluntarily checked into rehab on Aug. 29 one day after celebrating her 30th birthday—revealed that doing so was "the best birthday gift I could ever give myself."
"People look at you and go, why are you struggling? You know…no one can quite understand why you hurt so badly," she tearfully confessed to Katie, adding that transitioning from teen country sensation to pop star had taken an emotional toll.
"I wasn't a kid. It's as simple as that and so complicated at the same time. [You] like to see your kid be a kid, you know. And I didn't get any of those things," said the songbird. "So I feel like everything was kind of ripped from me and given to me and handed to me on a plate at the same time."
Hence rehab, which Rimes noted helped her deal with these issues and feel comfortable in her own skin outside of LeAnn Rimes, the Grammy Award-winning musician.
As for Cibrian, with whom she had an extramarital affair when both were married to other people, the "Can't Fight the Moonlight" crooner admitted she fought with the guilt she had after leaving then-husband Dean Sheremet for her Northern Lights costar, who subsequently divorced his wife of eight years, Brandi Glanville.
And while the public backlash wasn't easy, she has since learned to accept it.
"It was very, very difficult. I wouldn't wish it on anyone…and especially in the public eye to go through all of it," said Rimes. "I made my choices and I'm living with them. And I also have learned from them, and I've talked about this so much. But I know that…I'm not the only person that goes through this. There's so many that do."
Here's hoping her 30s are a little less rocky then her 20s.
