I have been dancing classical ballet for 12 years. Every day I rehearse in front of a wall of mirrors. Staring at yourself trying doing these,almost impossible, steps. While you pick at every little part of yourself it can make seemingly perfect girls a little crazy. One of my friends even refrained from eating regularly. But honestly with all of us looking at ourselves for 1-2 hours at a time judging every little movement, it could have happened to any of us.
