Adopt strategies to deal with fingernail biting. It's a reaction to stress and it is only making you more stressed. Have one of those stress balls. Get your nails done... The feel of painted nails is an immediate reminder not to bite them. Elastics on your wrists. When you get stressed you snap it to bring your attention back. It takes some practice to shift your habits. When you leave you don't want messed up nails so maybe concentrating on that as a goal will take your mind off the crap.

The following is something a group I worked with in a telemarketing job used to do. I think you can do it without involving other people. Start a list of worst/funniest/weirdest phone call of the day. The idea is to keep your mind creatively occupied and to add a little humor. If you do this make sure you don't leave it out. People might not get the joke.

Those are just some random ideas. You have a plan? Then it's only a matter of a ticking clock
