as soon as I found my t was leaving I started doing exactly the same thing - I took a step back - disconnected and put my shields up to protect myself just as you are doing - its only human to do that much much harder to stay open and attached when you know the relationship is coming to an end.

If your major prob at the moment is the anxiety over the move its ok to talk just about that - you deal with whats bothering you most at the time and you prob couldnt focus on anything else until thats dealt with - I know I cant - jmo - I hope it works out for you - can you discuss how you feel with your T ? that might help
