I started creating a checklist using a table in a word Document.
I've got my guidebooks and have made notes and dog-eared galore.

I've got my fabulous little adapter from Target for about $7.

My husband and I figured out the whole Skype-webcam thing to keep in touch for less.
I've got my 100GBP in Cash (which cost $165).

I've made copies of my Driver's license, passport, student ID, and credit cards and given them to someone I trust.
I haven't started packing yet, but I've been grouping things here and there so I can throw it all in.
I'm excited. And scared. I'd say its 50/50 right now. I'm just got a great traveler. Once I get there and I've overcome jet lag, I'm sure I'll love it! Not to say that I won't get homesick every now and then, but thankfully I've got some lovely classmates I know I can lean on from time to time and they can do the like with me as well.
See you across the pond!
Cheerio!
