Hello maymie: Really, there may not be much you can do here other than focus on your work & ignore them right back. (Plus look for another job if that is a possibility for you.) Beyond that you'll have to find opportunities for socialization & support outside of work since you're clearly not going to be getting any from your co-workers, sad to say.

Depending on your relationship with your boss, you could consider talking with your boss about what is going on. This might not even be a bad idea because you probably don't know how the harassment you're enduring is affecting how you're being perceived by those above you. But, of course, doing this could have a number of negative consequences as well. It could make your co-workers even more sour than they already are (if that's possible!) Depending on how you handled it, it could also be taken wrong by your boss. You'd have to handle it carefully. On the other hand, simply allowing things to continue to fester may be simply inviting further trouble. A more affirmative approach may, in the end, be for the best. This is a difficult situation. I wish you well...
