Have a think about a society you *might* be interested in - for example, I tried drama, singing, football, karate, and running - until I found something I liked - improv - and I stuck with that & had a blast. Also if there aren't any societies like this at your uni, see if there are any you can join at a nearby university - I know man met & UoM have a thing where people at either uni can join their societies, and they even accept people outside of university too. Don't worry; sometimes finding these things takes a while.
