Hi!
I completely understand your concerns. But first hand I can promise you that you will make friends and build close bonds while at university. Although most students like to go out drinking or clubbing, there are some who don't. I didn't drink at all during my first year at university, and I made friends by talking to my flatmates, having movie nights and going to different clubs and societies (I was in the Quiz, Debate and Musical Theatre societies), so maybe think about your interests and go to one or two societies and you'll soon meet people with similar interests.
Even the people on your course have similar interests as they are studying the same thing as you, so maybe suggest after a lecture to go and grab some food and get to know each other, because you are going to be studying with these people for at least three years.
I hope this helps. Please don't be too worried about making friends, because I promise drinking and nights out aren't what university is all about.
