You sound like a right barrel of laughs mate. I think some interaction sessions could benefit you in all honesty. Uni isn't just about locking yourself away in your room studying, why is it always one extreme or the other with you people? Believe it or not it IS possible to have combine "unproductive" activities and still do well uni.
Enjoy the next 3 years alone while missing half the point of what university is. You'll regret your attitude when you realize that your coursemates will do just as good if not better than you while also having a laugh, social life and developing more as a person.
