The Best Actress Oscar-winner for "Silver Linings Playbook" tells the September issue of Vogue magazine that she used to "lie in bed and wonder" about what would make her well-known.
She says, "It wasn't a vision. But as it's kind of happening, you have this buried understanding: Of course."
The 22-year-old also confesses her childhood was "unhappy" because she was "anxious." Her parents even sent her to a therapist.
It was when she got cast in 2007 in the TV series "The Bill Engvall Show" that her mother realized she no longer needed counseling because when she was acting it made her happy.
Vogue's September issue goes on sale Aug. 20.
