Yeah, I moved in yesterday (Saturday) and didn't do too well socially. Just said hi to a few of my flatmates, but not much else. I couldn't bring myself to go to the little party they had outside for new arrivals. I thought I was a lot better than this, but apparently not. But I've figured there's still loads of time, and so far it's not like I've met or spoken to someone like me who hasn't gone partying/clubbing/drinking or even someone on the same course. Plus I still have some flatmates to meet (I think) and there's at least one person in their room, so I'm not the only one having a night in from what I can tell.
No point getting hung up on it or forcing myself into uncomfortable situations when it's so early. It isn't like I can fake enjoying parties etc. for the rest of the year. I hate acting too haha!
