Jenny was admitted to the hospital after being found wandering the street, missing a shoe and appearing to have suffered some physical attack. She seemed to be in her late teens or early twenties. She was able to give you a home address and phone number, but remained very confused. When you called the phone number, her mother was overjoyed to hear that she was all right. She had left to go go drinking in a bar in Tijuana the night before. Jenny had not made it home from the previous day and her mother had been frantic with worry. Jenny could not account for the past 12 hours. A physical exam revealed that she had been sexually assaulted.
What is the diagnosis?
