You have to do what is the smart thing, and put the rest aside.
You want to get into medical school, yeah? You certainly must think on some level that you should, despite all the doubts. So you focus on your goal and don't even let yourself get in the way.
I totally used being a poor kid with a compelling story. Use whatever you have and don't feel bad about it. You're competing with all sorts of liars and cheaters and people hopped up on drugs and daddy's money. They're using all they got. So should you. Because doing whatever it takes (not unethical) to get the job done is exactly a trait med school wants. So is putting aside your own feelings, doubts, fears. Embracing your own awesome is somewhat requisite. Can you spend 5 minutes selling yourself? I hate it, it feels disgusting. But I've learned to do it.
So even just being ethical at this point, is something to feel good about. If you can be honest with admissions and you do get in, then that is and isn't on you, if you follow me. I ultimately decided I had to put my best foot forward, and if the admissions experts thought I should be in, who am I to know better than they? As long as you don't lie, you're not an imposter.
OK, so say some high tier school lets you in for being black. Go with it. It's up to them to decide who does and does not get in. You're putting your best honest foot forward. You don't need to do quality control for them.
Thing is, I believe in cutting people a break. How do you cope with the idea that you got into med school for being poor or for being black? Well, they wanted you for a reason. We always talk like it's about social engineering quotas. Bull crap. What did they think a poor kid or a black kid could add to the profession?
Explore what that is. And bring THAT to the table. I was generally able to deal with the guilt and imposter syndrome, by trying to be the best I could, and being sure that I was bringing whatever advantages being from the wrong side of the tracks, to help patients in a way unique compared to my colleagues.
The Ivy League schools know that they need to look outside cookie cutter applicants, or risk just being a cookie cutter school. It's culturally stagnant.
My alma mater was really committed to diversity (sorta needed to be), and you could definitely see what an effect it had on everyone, their learning, on a fundamental level. I'm not talking treatment at the point of care with patients. I'm talking about the culture and the effect students had not only on one another but also faculty.
The party line in academics about the profession always learning, always changing, is true. Or, it should be. The student does teach the teacher.
If you can leverage whatever reason they're letting you in for, to a unique contribution to bettering the care of patients, then you have just justified why they let you in, why you're there, and why you actually deserve to be there.
It's OK to be part of that process. Go ahead and apply. And when you get your white coat, don't apologize for a single second that you're getting it. Not even to yourself.
A lot of what we are taught is humility... I dunno, I would read about fear of success and really understand that concept.
