I totally sympathize with you. I'm in the midst of exactly the same thing---getting married this weekend, trying to get the visa the same week, and then moving over shortly after. It's insane!
I just moved my stuff out from my apartment to my Mom's house, and it seems that I have 3 x as much as I thought I had. I was hoping to get most of my stuff over to the UK by sending my fiance's parents and siblings home from the wedding with an extra bag each, but now I'm realizing that won't cut it. I'm going to get rid of a lot, but will still need to ship. I'm definitely going to be using M-bags for books as that seems to be the cheapest route by far...I've seen info about that on the moving board.
And the NY Consulate drove me mad! I was stalking them 2 weeks ahead of the day I wanted my appointment, and they were only opening up apointments for 1 week. So after a few days of watching this, I figured I could relax, and just check in the week before I wanted my appointment. Well I happened to check back a couple of days later, and found that the day that I wanted was up, so I grabbed it. I could have so easily missed it though. The weird part is the 2 days before my day weren't opened up yet.
Good luck with everything! I know how you are feeling!
