I have chipmunks in my backyard that are undermining my foundation. Think of them as striped rats.
My solution isn’t to move, my solution is to trap them in a havahart trap (they’re about 10 bux on amazon) and relocate them. My mother in law routinely relocates hers to the bottom of her lake, but I’m too softhearted to murder chipmunks (as destructive as they are) so I would suggest you start trapping your rats and either drowning them in the Charles or relocating them several stops down on the T. You can reuse the traps. At some point you’re going to run out of rats.
I think part of you is having a problem with hating a school that you worked so hard to get into. I’ve also hated places/ job that on the surface look like it should have been the most awesome thing ever. My solution to get through it successfully was to reframe it as not some place I liked, but some place that I wasn’t going to let beat me.
Don’t let Harvard beat you-yes, it sucks from what you’ve described, yes you hate it, but figuring out all the solutions to your problems rather than ditching and going to another school (which will present its own unique set of problems you will also have to conquer) is going to make you much more resilient and mature.
My suggestion for getting the ears of the powerful people at Harvard is to make friends with people who are good at this. The things in life I’m not good at-I have friends that will go to bat for me, as I do for them with the things they’re not good at. Throw a rock, hit an influential person at Harvard-they have to know how to bend the right person’s ear. They can’t all be floundering about there-figure out how they fixed it, and do that.
