Britney Spears: "I Worry All the Time."

Few people — and even fewer celebrities — ever have a year like the one Britney Spears has had in 2008.

From a nasty custody battle to hospitalizations to handing over the reins of her life to her father, this could easily have been the lowest point in her life. But then again, she's got a hit song, a new album, a reinvigorated relationship with her formerly estranged family — so 2008 hasn't been without its good side.

"The whole year has been a hell of a year for me," the pop superstar admits in the new issue of . "I didn't know exactly where I stood with everyone."

A big turning point for Brit was her triumphant return to the MTV Video Music Awards in September, one year after almost throwing her career away with a dazed and lazy performance at the ceremony. "When I received the awards and the audience stood for me, it showed me how much love is out there," she explains.

"Recording this album has helped take my mind off certain things," says Britney about her new CD, Circus, which will be released on Dec. 2, which also happens to be her 27th birthday. "For me, my music is therapy."

The one-time party girl, who has been photographed pantie-less with the likes of Paris Hilton and Lindsay Lohan also says that that's not the real Britney. "I don't like going out," she reveals. "I hate clubs. I hate being around too many people. I love my home and staying in bed and watching Dancing With The Stars or reading a Danielle Steel novel. I'm kind of boring."

With the clock running out on 2008, Brit's mind is on her resolutions for 2009. "I would like to stop worrying so much, because I worry all the time. And to learn how to be happier, just in general. I have to learn to take things not so seriously. And to stop biting my nails!"
