Now I've gone and done it.

It's done!
I finished packing (amazing what you can achieve if you forgo sleep) just as the big white van arrived. 45 minutes later I watched all my worldly goods trundling off down the street, wondering if I'd ever see them again. And now I'm off to Gatwick.

I'm actually leaving!
Hang on, does it still feel like I'm doing the right thing here?
Hmmm...
Yes, yes it does. Good to keep checking though.
Now where on Earth did I put my passport?
Huh?
