"I sit there and I look back and I'm like, "I'm a smart person. What the hell was I thinking?" News.com.au quoted Spears, as telling People.com. "I've been through a lot in the past two or three years, and there's a lot that people don't know," she added.
Britney, who has had an image makeover and is again trying to carve a niche in the music industry, stated that as a popstar she was always guarded, which led to loneliness.
"Sometimes I think I get kind of lonely because you don't open the gate up that much, you know I mean?" she said. "You're guarded. You have to be that way, so I'm kind of stuck in this place and it's like: How do you deal? And you just cope, and that's what I do. I just cope with it, every day," she added.
