Logic, Logic, Logic... Remember that you feelings are irrelevant, and just focus on the facts. It makes things easier.
When I moved for the first time, I was quite overwhelmed. I felt spread thin without anything familiar to fall back on. Heck, I didn't even have a proper bed to sleep on.
As I remember, I had been up all night working graveyard shift; then I packed a load of stuff and went to my new place (about a 40 minute drive) and found myself wandering around like a zombie in the middle of a summer afternoon in a strange house with no curtains and the sun glaring in, after about 35 hours without sleep. At that moment, I felt REALLY REALLY strong emotions which were telling me that the whole concept of moving was a huge blunder. (In retrospect, it was not. It actually was necessary.)
It took me a while to get settled in, but soon the newness wore off and everything was once again comfortingly monotonous and boring. (It probably took about 90 days before things felt "normal" again.)
In more recent times, I had to move again. It wasn't overly traumatic the second time around; just a pain. Nevertheless, anytime you change houses, it takes at least some getting used to. One tip: find some DVD's that you watch all the time and are familiar with. If you don't have to do anything, sit and watch them. It will help distract you from the newness of your surroundings and help create a mental interface which connects your current situation with your previous one via a common similarity.
Good luck settling in.
