I think everyone at some point in their lives has gone through the move to a new city and meet new people moment. It's not easy but you learn a lot even if it is a negative experience. I totally understand how you feel. I moved from Boston to LA for grad school last Sept and it took me a long time to get adjusted and meet new people. Like sigmagirl, I didn't receive a response from the ADPi AAs at first but after forcing myself to go to a couple of events I've meet enough people that if I need someone to talk to or hang out I can. Keep in mind that even if you dont click the first time you meet someone it doesnt mean they wont be someone you shouldnt get to know better. Another great thing is to check out the campus for events or activities where you could meet people. Is there a student union you could hang out at? Does the school gym offer pilates/yoga/etc classes you could take? And hey if all else fails plan a Boston GC get-together and you can meet some of the people from the site, I'm in town for another 7-10 days.
Chin up it gets better, enjoy your time in Boston its a beautiful city with lots to offer (but I'm slightly biased

) PM me if you need any pointers or if you just want to vent
