In the last year, Stone has become America's golden girl, staring in major films including "The Help," "Crazy. Stupid. Love" and "The Amazing Spider-Man." But the actress opened up to Vogue in its July issue about her history with panic attacks that began when she was eight years old.
"I was just kind of immobilized by it," she told the magazine.
"I didn't want to go to my friends' houses or hang out with anybody, and nobody really understood."
After years of therapy, Stone, 23, was able to work through her fears and start her acting career, but she still gets attacks from time to time. She recently told Interview magazine about her anxiety in filming "Easy A," her first leading role. The actress admitted she has never seen the film because it brings back bad memories of her anxiety.
"I was a wreck during that. I didn't sleep much," she said in Interview magazine. "I remember the day I wrapped 'Easy A.' Getting into the car as the sun was coming up because it had been a night shoot... It felt like a house had been lifted off of me. I felt a great deal of pressure making that movie, because in my personal life at the time, too, things were just... It was like a hurricane."
Paula Deen, the famous chef, opened up in May about her battle with anxiety, which kept her from leaving her house for weeks at a time. That kind of anxiety, called agoraphobia, gave her panic attacks. She said she became terrified of dying after the death of both of her parents.
"I would have panic attacks and my arms would go numb and you feel like you're having a heart attack," Deen told Entertainment Tonight. "And I kept a brown bag next to me at all times so I could quickly breathe in it. It's just a fear that would come over you like no other."
Deen said prayer and spiritual reflection helped her work through her battle with anxiety.
