Thank you very much for your quick and informative response! I was thinking sort of the same thing about the depression ordeal and wondered if it may be best to just not mention it and to make up for it with other things.
The Native-American was in jest :P I definitely wouldn't want to accepted on the basis of race, especially when I don't regularly identify myself as such.
My EC's are scattered, yes! Sadly, I am plagued with too many interests. I do have somewhat of a focus in medicine and science (some EC's I didn't mention like county science fair awards, local summer healthcare programs, etc.), but I really am just interested in a wide variety of things. I will most likely heed your advice and try to develop my medicinal focus in my application.
Recruitment is not likely, unfortunately
(Unless any of Columbia's sports teams need rather mediocre athletes!)
Again, thanks a lot for your insight.
