Bittersweet Lies (2002)

After their latest drunken stunt playing chicken with a speeding train, Cassie and Renee wind up in a clinic for attempted teen-suicide victims. Among the eclectic mix of patients are a prissy valedictorian, a goth-girl, the 'perv', and a religious fanatic. Brooke is a compulsive liar who discovers an identity-theft scam going on from within the facility, but no one believes her. The teens come face-to-face with their past as Brooke tries to save their future.
