Well, welcome to the UK! BTW, the winters here are better than where you're from. You'll love London. The theater district is fantastic! And London "Broadway" is a heck of lot cheaper than NYC! (please start with "Phantom" at Her Majesty's Theater)
Museums galore, history coming out your ears. You could stay five years and see something new and interesting every weekend. The people are very friendly, if you make the effort to meet them, as many i've met are not forward enough to walk up and say hello. They can be a bit reserved.
If you should actually get bored, or more likely, sick of the weather, Europe, all of it, is a 2-3 hour plane ride away. Hell, there's a train to Paris!
Should you get homesick, go to "Bodean's Bar B Q (6 locations) all American and US sports on TV.
Your job? If your gonna leave, change careers. You've got an education and your smart, there's always a job.
Have fun, when you're in a nursing home, this could be the adventure you're happy you went on
