AceShowbiz - Kate Bosworth used her own real-life experiences with anxiety to help her play a depressed college student in "Another Happy Day".

The blonde beauty reveals she has suffered from intense panic attacks, and admits she used her struggles with anxiety to fuel her performance as Sam, a self-mutilating woman, in the dysfunctional family drama.

She tells Nylon magazine, "I'm not someone who is a stranger to panic attacks or anxiety... I've had my fair share of on-the-verge moments in my life, so it was really kind of tapping into my own life experience, and that gets a little weird. It's what we live for as actors, to soar to that moment when you sort of leave everything behind. But it's also the scariest because you're getting lost in yourself and touching a nerve that, on a day-to-day basis, you armor. Sam wasn't fearful of the dark places, and I think I have a healthy amount of dark places to go to."
