Hey
@The Monk,
Don't worry about asking questions, no matter if they seem unimportant or a matter of life or death!
I can't answer all of your questions, but I can answer a few about what I would class as halls life.
With food - it can vary. If you want to feed yourself then that'll be absolutely fine. However, you might find that it's a lot cheaper to eat with others than to buy all the stuff for yourself. You'll also find that you eat healthier meals when cooking as a group as you can afford the expensive things to keep it fresh. As I said, if you don't fancy any of this then that's totally okay.
Halls is a hectic place, most people don't eat at the same time and they're waiting for the cooking facilities to become available for their own meals. Therefore dinner tends to be a rolling machine of people. Someone will be eating while someone or a few people are cooking. I rarely had a sit down meal with flatmates in halls, only when we went out for food. You might find that as you get to know your flatmates, you might even want to do this? A lot of people will take food back to their room anyway as they'll be mid-assignment or in the middle of a TV show.
You won't seem like a loner if you stay in your room and watch Netflix occasionally. Everyone needs 'me time' and that's well respected in halls. I wouldn't advise that you do that in freshers week as it's cutting off opportunity to make friends and settle in.
With the xbox, you'd presumably be keeping this in your room with a TV? That's probably the only way that you can know it's 100% safe. I wouldn't recommend having a shared xbox in halls, but maybe in housing during your second year.
I can't answer anything about History, but I thought I'd recommend that you could potentially look at your anxiety and explore options to minimise its effects. Most, if not all, unis have support services that offer informal counselling. It might be a great opportunity to nip it in the bud? Look out for these services when you get to uni.
Any further questions for me? Just make sure you tag me, quote me or mention me (like Twitter).
