If it's alright I'll start with a bit of background info - during school from around the age of 6-15 I was bullied pretty much every day, and ended up not talking to anyone, not doing any social things, and generally staying in my room playing games online. Also during this time, my parents were getting divorced, and ended up living with my dad (who I far prefer), but the issue with him is that I've never seen him go to a social event, or just ever go out for any sort of enjoyment.
After GCSEs at 16, I finally built up the courage to tell my dad that I was being bullied badly at school, and wanted to leave school to a different place for A levels. I ended up going to a local college, and started out with the intentions of just keeping my head down, not talking to people, and getting the A levels I needed for university. Anyway, a month or two in, the person who sat next to me in one of the subjects realised I wasn't really hanging out with anyone, and introduced me to a group of people, who throughout the 2 years of college I had some really great times with, and was definitely the best 2 years of my life. A couple of things which I really remember was at the end of college, I was just waiting at the bus stop, and a couple of people I knew were walking out of college to a different bus stop, and they just waved to say 'hi', and it just felt amazing. Another thing which I loved was that for my 16th birthday at college, no-one knew, I just sat in the canteen, and I remember (sounds so pathetic) buying a can of Monster to celebrate it, but next year after being introduced to people for my 17th, someone allowed us to use their house, and had about 15 people round their house for a party, and had people buying cake and stuff, which was just amazing.
College ended, and really only stayed in contact with a few people, (really close to a couple of them), and managed to get into uni which I was really excited for, but this is where the real problem is. I'm guessing it's a mixture of the things that happened to me during school, and that I'm now quite far away (other side of the UK) to the people who I got so close to during college, but I'm really scared of people, and talking to/seeing them. Again sounds pathetic, but I'll lock myself in my room all day, and if I'm hungry/need the toilet or something, I won't leave my room until I can hear that all the other flatmates (who are all cool people, never been mean to me or anything), have either gone to bed, or gone out somewhere, and only then I'll quickly scurry to the toilet/kitchen and get whatever done.
I keep telling myself that they really could not care less if I go to the toilet, or if I'm making some lunch/dinner, but I'll unlock my room, step outside, hear voices from the kitchen and just get back inside my room and lock the door as quick as I can.
If there's any advice people could have to make me less... I have no idea whether it's scared of them or what, but if anyone has any advice to make me somewhat more 'normal', it'd be greatly appreciated, thanks.
