I suppose it’s a moot point by now, but I’m a little surprised you didn’t opt for a semester/year abroad junior year as a way to cut your sense of isolation at Williams. If you had done so, by the time you returned to campus, you’d have only one year to get through. Since you’re already facing an extra semester as a transfer, is withdrawing temporarily for spring semester (perhaps working/volunteering at a hospital) and taking a semester abroad/away next fall at Williams (as a second-semester junior) out of the question?
