If you want to become a doctor why don't you go to another college.  Save the slot for somebody who really wants to be a pilot since the the Air Force Academy is the best way to be a pilot.  If you wanna be a doctor there are plenty of other routes that would not contain near as much stress.  Now, if you wanna be an officer in the Air Force, that's a different thing.  By all means, try for the AFA.  Oh, and going there just for a free education is a major turn off. Don't tell people that's one of your reasons.
