New excerpts from Britney Spears’ upcoming MTV documentary, For the Record, have just been revealed by the U.K.’s The Sun, in which the pop star says that while her career is back in the zone, her controlled existence in the wake of her breakdown last year is often a struggle.

“There’s no excitement, there’s no passion. I have really good days, and then I have bad days,” says Britney, whose father, Jamie, continues to serve as permanent conservator of her estate. “Even when you go to jail, you know there’s the time when you’re gonna get out. But in this situation, it’s never ending. It’s just like Groundhog Day every day.”

“I think it’s too in control,” she adds. “If I wasn’t under the restraints I’m under, I’d feel so liberated. When I tell them the way I feel, it’s like they hear but they’re really not listening. I never wanted to become one of those prisoner people. I always wanted to feel free.”

For the Record premieres Nov. 30 on MTV, two days before Brit turns 27 and releases her sixth studio album, Circus.
