They're both right, but it'll pass, just drink more beer. I think everyone gets a bit homesick when they go to uni, it's natural but give it some time. It's a bloody 'orrid feeling though.
I know that the feeling was 100 times worse when I left uni and moved back to my hometown. I was different but everthing else was exactly the same. It's all relative so enjoy uni while you can, it goes bloody quick and before you know it, you've got a sodding job
After a little while, you'll have a good group of mates and who knows.........I met my wife at uni.
