The 30-year-old country singer performed for fans Friday night at the Eau Claire Regional Arts Center in Eau Claire, Wisconsin, just days after she entered treatment for emotional issues.

"I'm totally cool and so happy. I think I'm about to cry," the singer said to the crowd. "Thanks for being awesome fans…patient and understanding."

Rimes performed a 14-song, 70-minute set that gave fans an intimate look at the turmoil surrounding her life and even affirmed it with a quick disclaimer while on stage. "I'm pissed off at a lot of things, and I just can't say it," Rimes said. "So, it comes out in the music." Her husband Eddie Cibrian was back in Los Angeles during Rimes' Midwest stint.

The blonde beauty is scheduled to perform a series of concerts later this month and her new album is scheduled to be released next year. She even took time to tweet her appreciation after the show, saying, "Thanks to all my wonderful fans in Wisconsin. You showed me an amazing amount of love and respect tonight. Love you always."
