I'm glad you decided to go to your program. I feel for you that you will have to uproot your life to do it.
I think too many people try to get out of their match without realizing what it did to fellow participants. If you rank a spot that you can't go to, are matched there, and don't show up, that could mean that someone else had to scramble or even worse didn't get a spot.
Thanks for being a grown-up.
