Is my university social life doomed because I don't like clubbing?

Having been at University since 2009, I've not had a doomed social life because of it. My hatred for clubbing has certainly limited the things I can do with mates at times, but it has never gotten in the way to the extent that I was never able to make any friends. Sam the man pretty much nailed it above: you'll get mates who mutually want to do things together. Having people who just try and force you to do things you don't want to do isn't much of a friendship, so it's all about being honest and putting yourself out there, to engage with different groups with mutual interests. Hopefully, your student union should have a variety of societies for a whole range of different hobbies, activities, fandoms etc. Make an effort to sign-up and attend their events! They usually make it clear which of their respective events are for clubbing (if any), and which will be more relaxed.

As sam the man mentioned, not everybody at university is a party animal. I even ran the LGBT society for numerous years without being an avid clubber, despite them being clubbers themselves. We'd have some drinks at the Student Union for a few hours, where it was much quieter and relaxed, at which point I'd arrange for somebody else to go into town with them whilst I went home. It never once got in the way of things, and it even became something of an in-joke with them to try and jokingly convince me to go out clubbing, knowing it would induce a self-righteous rant about how awful it is. My favourite line was something along the lines of "Only us young people could be stupid enough to go to a place so loud that communication is impossible, and call that 'socialising'". Anyway, my point is that there's a broad range of people you meet at university, and most people are just out to have a good time and will accommodate your wishes. Sure, some may try and peer pressure you into things, but a little self-confidence and assertiveness will fix that. Additionally, you've got to expand your friendship circle beyond 4 people, and at that point you'll develop friendships with people who have mutual interests to you and who will respect your wishes. I never needed clubs to develop a circle of friends at Uni, nor have many other peeps I've met over the years.
