Hang in there, you are doing the right thing as far as Wes.
Job stress isn't good, just try to go in and do your job and go home, don't sweat the small stuff as Erma Bombeck used to say. I know easier said then done, but you don't need anymore stress.
If you have to take a leave of absence, you will need a dr's note though.
Your stronger than you think........
