With 2 weeks left to go, I've done a few more bits I thought I'd list, which are mainly minor things but could make life easier during the big move. -

Take a mortgage holiday - If you are renting your house out and can do so, take a payment holiday so you skip the month payment when you are moving.
TV licence - I've now cancelled this and was amazed to hear I am getting £60 back as you pay about 5 months in advance apparently!
Credit and Debit cards - Make sure none of your cards are going to expire in the next few months. I have got new debit cards and credit cards with an expiry date far in the future.
Contraception (ONE FOR THE LADIES) - if you have the pill, make sure you have enough to see you through until you can make new arrangements. You can get the pill in Cyprus, but last time I got it there, I had to see the doctor for a prescription and then go to the chemist to collect. - The same would go for any other medication you are on I guess.

As for what is going through our heads right now with so little time left - (I think this is what Cypriotsid was after) -

AARRRGGHHHHHHHHH!

I think that about covers it.
