I can relate totally to what you're going through. I was an electronics technician/customer service person in a high stress position for about 10 years & finally had a real good long talk with myself about my quality of life. The way I see it, we spend well over 75% of our lives in a work environment & for me the stress was making me physically sick every day just getting up to go to a place I'd come to despise. I know that the economy makes finding a good job & staying in ones chosen career difficult but if you absolutely cannot deal with these people it may not be the best place for you to be.
Perhaps try asking them out to lunch on a one on one basis & see if you can come to some kind of amicable ground. Sometimes just airing the problem can help to get solutions.
Good luck to you
