I’m wondering if you are feeling homesick or regret?
It is understandable that as the excitement and newness of going away to college fades, as the long and warm days turn to cold and rain, that you might start to think you’d rather be somewhere else (perhaps closer to home). It’s almost Christmas break at many schools but when you return you can double-down on clubs and activities to feel more involved and at home.
Since you mentioned being waitlisted at all those schools keep in mind that at many colleges these days being on the waitlist doesn’t mean you were “almost” in. They waitlist thousands even though they know from the experience of years past they won’t admit most of them. Some say it is to allow them to replace admitted students that don’t accept with a similar student. That may be part of it, I think colleges also do it to send a signal to the HS juniors who treat it as almost an acceptance and decide to try their luck (selective colleges love a low yield which means they need lots of applicants).
