Jennifer Lawrence underwent therapy as a young child to deal with social anxiety issues after struggling to adjust to school life.
The Hunger Games star reveals she was an energetic child, but her personality changed completely when she began formal education.
She tells French magazine Madame Figaro, "My nickname was Nitro, as in nitroglycerine. I was hyperactive, curious about everything. When my mother told me about my childhood, she always told me there was like a light in me, a spark that inspired me constantly.
"When I entered school, the light went out. We never knew what it was, a kind of social anxiety... I went to see a shrink, nothing worked."
Lawrence quickly learned she didn't need professional help and instead found different ways to channel her energy and deal with her issues.
She continues, "One day, I begged my parents to take me to a casting. We went to New York, and that's where I started acting. Just on stage, my mother saw the change that was taking place in me. She saw my anxieties disappear. She found her daughter, the one who had this light and joy before school.
"I finally found a way (to) open the door to a universe that I understood, that was good for me and made me happy, because I felt capable, whereas before I felt worthless."
