I know exactly how you feel! We didn't buy a house, but somehow everything is down to the last minute for me too. Todd got really busy at work in the last couple weeks and as it turned out, my supposed part-time job became not only full time, but also over time for the past 2 months!
We managed to get our last newsletter out in the mail (along with some extra goodies - which were totally unnecessary, but I really wanted to do them) yesterday. Now we have to focus on making sure our bridal party and parents all know what is going on! I definitely will not be able to relax and enjoy the day of if I am getting asked a zillion questions!
