RIT can be a pretty miserable place in the winter, I know from personal experience. Maybe you have some seasonal affective disorder in addition to your other issues? Vitamin D in the morning and melatonin in the evening might help, and of course exercise is good for all sorts of mood related issues - so joining one of the clubs might be a good idea, or take a class like fencing (well, I enjoyed the fencing class anyway...) or start rockclimbing at the barn. Clubs might be a good idea in general, actually - the people in the go club were not stupid when I was there and it was nice hanging out in Java Wally's.
