Hey man (if you are male), you sound depressed. Seriously, sleeping so much is not a good sign. If you don’t like NYC, well then Columbia was never going to be the right place.
Whoa, how wrong you are. Take it it from me there are many relatively mediocre students at every Ivy. Every one of them.
But the top end is extraordinary. Without revealing too much information I was friendly with one particular student who graduated valedictorian at 18 years old (yes, 18) and went on to world level recognition in his field. My best college friend was salutatorian and went on to found a firm and retire with $500M+ by age 40. Both had smarts at an otherworldly level - the gulf between them and the “average” HYP kid…
…well, if you have some spare time instead of sleeping, read Heinlein’s Gulf. (“The gulf between us and them is narrow, but it is very deep. We cannot close it.”)
Try to seek out the smart kids, and see if you can hang with them intellectually. You’ll need to if you want to have a hope of transferring “up.” Good luck!
