Calista Flockhart told PEOPLE Magazine weeks ago that she does not have an eating disorder. She now concedes, however, that she does suffer from panic attacks. "I'm riddled with insecurities about the future," the "Ally McBeal" star, 34, says in the Jan. 3 Parade magazine. "In the back of my mind, I think: 'If the show's canceled, I'll go back to the theater.'" Flockhart, who won a Golden Globe for her portrayal of the flighty young lawyer Ally, first achieved success on Broadway, getting raves for playing Laura in "The Glass Menagerie" in 1994. "On-stage, I feel at home, comfortable, accepted, whole. It's like a drug for me," she said, laughing. "It doesn't sound too healthy, does it?"

Factoid: A&E's "Biography of the Year" was Ally McBeal.
