Definitely keep going to the societies to the ones you love doing. Dont give up on them because its still good for you socially to get out and about of the house. Uni students can be very hit and miss at times and cant always commit to things. if someone does agree to come out, perhaps things outside the society like a pub quiz is good because it keeps things interesting thoughout the evening, and who knows, perhaps you might meet other fellow students in the pub as well. Thats how my daughter ended up making friends. Some were drifiting in and out all the time, and shes come to accept thats how it is, but a couple are close.
