I actually called and asked many of the schools I am reapplying to and they all told me I can use my essays form last year. Many of the schools told me that they lock all of last year's apps up after the cycle's over and will no longer look at them. They told me that they wouldn't have any idea that the essays were the same as the year before. I made some alterations on mine, but nothing serious. 1 interview invite so far, and I'm an August MCAT taker.
