says she tried to block out the hurtful things
people said about her over the past few years. But at a certain point, it gets to be too much.
"I think it's really hard to deal with Twitter and Facebook and all these social media outlets," the country singer, 30, tells the Boston Herald
in her first interview since undergoing treatment
for stress and anxiety.
"It's hard to take it day after day of reading and seeing things that someone you don't even know says about you. As much as you said you don't want it to penetrate, it does, because you're human."
Treatment, she says, helped her focus her energies on herself, not on what other people were saying.
"I've been in therapy my whole life," the Grammy winner says. "I like going. I like being able to have that third-party input and someone to listen that has nothing to do with your life. Everyone has an opinion of how I am and how I should be, and now I'm focusing on how I want to be."
Turning 30 recently
was also a milestone emotionally. "I had some wonderful times in my 20s, but your 20s are hard," Rimes says. "It was a lot of learning experiences ... and a lot were thrown at me publicly. I was ready to embrace 30."
Rimes is now focused on family life with husband Eddie Cibrian
, as well as her career – she's set to hit the road for a U.S. tour this fall and release a new album in the spring.
