Cruz Is Insecure About Her Acting

The actress admits she makes herself miserable stressing and worrying about every project she takes on - even after she scooped the Best Supporting Actress Oscar earlier this year (09) for her role in Vicky Cristina Barcelona.

Cruz says, "Every time I make a film, I feel like it's my first time... I always think they could fire me. I've ruined my own happiness and created problems with my friends because of this tendency. It takes discipline for me to stop worrying."
