In my case, sending in this paperwork is imperative, so I'm doing it. Hopefully, it will be in the mail tomorrow.

Do you HAVE to go to this conference? Maybe it won't be as bad as you're imagining. Do something nice for yourself like buy a coffee on the way. Make sure you eat breakfast so you feel good. You may not know how the day will go, but you can look forward to a Dunkin Donuts or Starbucks coffee. If you don't like coffee, maybe iced tea?
