If you're really not enjoying it at all, seriously think about dropping out now, before the start of second year.
Once you've started your second year, the way finance works makes funding a new degree really difficult. So have a serious think about if this is what you want, or if actually, you don't want to go back, now!
The first time I went to uni, I really enjoyed the social aspect. I was surrounded by interesting, arty people all the time, and had great fun going out and exploring London. However, by christmas, I'd realised that wasn't enough, and I basically hated my degree course. I had no passion for the subject, and didn't see a future in it. Truthfully, I'd been talked into it by my sixthform, as I was struggling to chose what to do. So, I dropped out and came back home.
I worked for about 6 months, and that autumn looked through the prospectus of my local uni, just out of curiosity. There were two (very closely linked) courses that really grabbed my imagination. They were much more closely linked to things I'd always been interested in. So, I applied, thinking if I changed my mind, I didn't have to go. I did go that September, as after working 18 months in offices, I was pretty bored! I'm now much more passionate about my course, and have really enjoyed the last two years of uni life. I've met some lovely people, too.
I guess what I'm saying is that if you're not happy, then you don't have to stick it out for another two years. It doesn't mean uni isn't for you, but that course at that uni probably isn't. You need to do what's best for you, not what's best for other people.
