Don't worry Jen, I felt exactly the same at Uni.
To be honest the whole "student scene" never appealed, I already had many friends from before uni (same friends I have now 10 years on, yes, have had a 10yr uni career!) and found a lot of others really immature. However, it did mean I was lonely during term time, even when out getting drunk!
However, in my second year I started playing rugby (which I realise may not be for everyone), but it really helped. The team was a complete bunch of misfits, yet lots of them have become very good friends and stayed so. Joining a club or society means you don't have to conform, so you can just be you, and you get to meet people who you may not otherwise bump into. Also people who you think you have nothing in common with, you'll be surpised to find out you do.
As your course is going well, just look out for opportunities to meet other people. It takes a while, particularly as in your first year you're all shoved together, but you will find real friends when novelty of the first year starts to wear thin. I have a lot more close friends that I acquired through rugby (either as players,or friends of players etc) than those who I was in halls with or who did my course.
Getting a job or joining a society gives you access to a much wider network of people. You may find one person who you get on with, then they'll introduce you to their current friends etc. etc.
Don't worry about boyfriends, they're like buses - none for ages then three come along at once!
