I am so sorry you have to deal with mean spirted females!! I have two daughters and they too are having issues with people at work. It made me think of my past... now I am a teacher and pretty much stay away from "adults".. but I do remember the days... ugh!!
My advise, do not let them win!!!!!!!!! If you do move on there will be people like them there also. Do your very best, have someone you can vent to and stay out of trouble. Whatever you do, don't "engage" or take part with them. It will not do you any good to "pay them back"! They may all not be as bad as it seams, some are just following the leader. Not that I have much respect for the followers... but you maybe able to win some of them over if your actions prove you are the good guy.
I wish you the best of luck... at least you have yt to "talk" to
