Uhhh... Do not contact admissions over this. I am struggling to understand exactly why you feel the need to self-flagellate over an earlier draft of your personal statement.
So you sent a draft to some recommenders in which you said a story that truly happened to you happened to your brother? And then after thinking it over, you scratched that aspect and submitted a final version that correctly put you in the shoes of the trauma? And now you're worried that your "dishonesty" will come to light by your recommenders contacting your soon-to-be medical school?
If I correctly interpreted your situation, absolutely do not move forward with any of the plans you are contemplating. And congrats on seeking out the help you need to better yourself.
