The former child star became a sex symbol in the 1970s after portraying Princess Leia in the Star Wars trilogy.
At 52, Fisher is now appearing on Broadway, in her one-woman play Wishful Drinking.
But the show's success has been marred for the star, who admits she can't stand to watch replays of herself onstage.
She explains, "I invite people to my show not to look at my house (body) but to listen to my furniture (performance), because I'm a little on the mansion (heavy) side right now and struggling with it."
But Fisher admits she's trying desperately to put her self-consciousness into perspective.
She adds, "That's a minor thing. That's not my biggest problem. It's a nosebleed, high-class problem, but it makes you vulnerable."
