That doesn't sound like a pleaseant experience at all.  I'm sorry your first days here have not been the best.  It will get better, I promise you.  I remember the first week I was here.  I came without my family and a combination of the exhaustion from getting used to the time change and the stress of having to set up house by myself in a new land was overwhelming.  There were a few times where I felt ready to snap.  But it got better for me and it will get better for you too.  Don't lose that excitement you had when you were planning your move and still had when you first arrived.  If you need anything, let me know.
