Its getting hard

So I have been here not even a week and I don't think this head ache is going to go away.  I have hit my first wall.  The first few days were good, I learned a lot, I was loving the people, but now everything feels like a blur.  I am always tired.  I just feel completely drained.  I have hit the first stage of culture shock, and I need to be careful what I do next.  I can easily fall into a slump where I learn very little because I put too much time into tv, movies, Facebook, and other "American" things.  Although that is all I want to do.  I want to isolate myself right now.  It is so frustrating when I know I can't.  I don't know.  This is the hard part of the trip.  The adjustment.  Keep praying I will need God.  Thanks, I miss everyone!
