Well your probably packing right now with thousand thoughts going through your head, just don't talk yourself out of going
Everyone has fear going in its normal, you will be all settled in in a few days as you get comfortable with the routine and new people. Before you know it your time will be up as you head out feeling healthy and ready to start living and practice using the new tools you have acquired.
After 60 days in some ways i didn't want to leave, good luck
