They don't have the bandwidth to consider each of us as an individual, special snowflake. Each of us is waiting to make alternative plans, each of us wants to get into medical school, each of us looks nearly identical on paper. So, to say that you can't "conceive of treating another human being like this" is grossly misrepresenting what's going on -- they're not condemning you to a concentration camp in North Korea; they're not lashing you to the point of unconsciousness with a bull whip. They're dealing with thousands upon thousands of applications and trying to manage ever-increasing volume each year.
You're typing on a publicly-accessible forum, so I assume that you know that your words are candidates for scrutiny. What you're currently going through is not the end of the known world: you're waiting to hear back on continuing higher education -- do you not realize how incredibly freaking lucky you are to be that position? Maybe I'm just weathered from life -- I'm older, I had a crushing childhood, I've gone hungry, I've had friends mowed down with semi-automatics, I've watched my dad brought back from the brink of death on several occasions -- but if you take a moment to step back and really read your own words -- REALLY try and contextualize what you're saying -- I think you may understand my reason for shaking my head at this.
I wish you the best. I do. But as you're gearing up to care for human life, know that there will be FAR graver circumstances in your future.
