Help!

With six weeks to go, things were looking pretty good. We'd sent the invitations, were working on the last details with the florist, sent our rings to be engraved- in short, we'd taken care of a lot of things. Same with 5 weeks to go- we ordered our guestbook, finalized some of the gifts for the bridal party, wrote shower thank you notes- and life seemed manageable. There were quite a lot of things left to do, but since classes have ended for the term, once my students' exams are graded next week, I'll be on summer break, giving me plenty of time to take care of the last things.

Cue yesterday.

For reasons completely unrelated to the wedding, the 4 weeks of summer break that I thought I would get has vanished, as things somewhat outside of my control have now inundated me with a ton of work to do. (Basically, my second comprehensive exam for my PhD is a paper defense. I thought I had the paper in good shape, but it turns out it needs a ton of work. Basically, I need to rework my entire paper in a different framework. I need to take the exam before the wedding, which gives me 2.5 weeks to redo the paper.)

Totally manageable, especially since classes have ended for the term, except that I am getting married in a month. Enter panic.

What have you done to keep things under control?
