Hi there,
I'm sorry to hear that you haven't been enjoying your university experience so far. But keep reminding yourself it's only been two weeks. You're still settling in and getting to know people. I'm pretty sure most people don't make their university friends during the first few weeks - it can take a few months to find the people you click with. So try not to get too upset about not making friends yet, you still have so much time to find them!
About your flatmates, if you feel comfortable it might be worth letting them know that you're anxious and autistic, and how this can make you feel overwhelmed by the loudness and new people coming in all the time. It might not change anything, but at least they can be aware and hopefully won't perceive you as being 'rude' or 'antisocial'. I'm also anxious and autistic so very much understand how you're feeling - if the overwhelmingness get's too much, remember you can always get in touch with your wellbeing department who should hopefully be able to support you.
My advice on making friends would be to try to be consistent. Keep going to society events and talking to people. You'll hopefully start to feel more comfortable over time as you get to know them, and they could be shy as well so if you keep talking to them maybe they'll start to get more chatty and engaged. You could also try to talk to more people as this will increase the chances of finding people that you click with.
I know it's hard not to worry about housing while people start looking so early on, but try not to stress. If you don't feel comfortable getting a house with anyone yet, you could always look into private halls. It's similar to first year university accommodation - your own room in a flat with a shared kitchen (or a studio if you want more personal space). I stayed in private halls for my second and third year, and lots of other people choose to as well. Some common providers include Student Roost, Fresh Student Living, CRM students and Host.
I know it can be upsetting to feel like you're not making friends despite all your effort. Keep trying though! So many different people and personalities go to university, so there's a really high chance you'll find like-minded people!
It's only been two weeks. Just keep being yourself, be consistent in meeting and talking to people, and don't be afraid to talk to new people.
I wish you the best, and hope this helps!
