Develop your coping mechanisms. Start a group email with friends so if you work on a computer you have a friendly email to make you smile. Group conversations keep momentum much more than one on one emails.
Always pack a yummy lunch so you have something to look forward to!
Mentally play games with yourself. Like if a coworker has a habit of saying the same word all the time keep a running tally and mentally bet what it will be each day.
Honestly most jobs suck. Just sit back and bide your time and your b-tichy work mates will implode on themselves. I've seen it happen time and time again. They get all chummy chummy. Then the proverbial hits the fan and they all hate each other. It's coming. Just wait.
