I am also nervous as well. I lived in my Fulbright country (Lesotho) for almost 3 months before starting graduate school, but all the logistics of finding housing and setting up my research study has me anxious. That combined with the fact that my graduate advisor is obsessing about my safety has me a bit on edge.
I am leaving my fur babies as well...I know they will be in good hands, but that isn't going to make me miss them any less.
I am sure once we all get to our various locations and get settled, we will love it and not want to leave to come back home.
