3 weeks until orientation

Having only three weeks left until my orientation in Miami on June 16th, I'm feeling a mixture of emotions.  Excited?  A little.  Nervous?  I'm getting there.  I guess I'm still waiting for everything to sink in.  The idea of living in a country for the next 26 months where I've never even visited before is hard to wrap my head around.  Not to mention moving to a different continent away from all my friends and family, where I do not know the customs, language or the people.  (Yet!)  I'm not worried, I'm sure i'll start freaking out within the next week when I have to begin thinking about packing.
