I can understand where you're coming from to an extent, I don't drink, I don't like the club/bar environment, but maybe these people are just trying to be friendly and include you in their celebrations that uni exams are nearly over? However I can understand why you have been annoyed by it, if you think that they're just saying it in a false kind of way or if they're trying to change you to be like them in a bullying way. I can also totally sympathise with the idea that people interfere where it's really not necessary, I seem to be surrounded by a bunch of weirdos (apart from my good friends obviously) who if I do ANYTHING seem to want to report it to everyone they know, even if it something as simple as saying that i would prefer to eat at X rather then Y. Strange, and also irritating in the long term. Like toy soldier I also play my cards fairly close to my chest, i don't feel the need to tell someone i have never met before every minute detail of my life, although i do open up a lot to my friends. I think what irks me most is how false people are.
