If you can write about the 'booing' compellingly then you *could* choose it. I think that the 'culture shock' of high school should be considered an acceptable adversity and, if it were me, I'd write about it.
Speaking entirely in generalities: Most of the people who experienced true adversity with irreversible consequences in COLLEGE are likely NOT applying to medical school. This isn't true across the board, of course, but let's face it, if your adversity was really that bad in college, you may not have done so well grade-wise. And if your grades suffer, you probably won't consider applying to medical school (usually). Or at any rate, you'll be making up those bad grades for quite a while before you DO apply.
Adversity = not a great topic 👎.
