Stress is killing me

The stress at work is really bad lately. It is causing me tummy problems and headaches and insomnia. I DON'T LIKE IT! My boss is still out of course with his back surgery and I am trying to do it all. Today is my first month end that I have to do it all, and do it all alone. I am very stressed because our business is down and that makes the other employess ill and cranky. I could not eat supper last night because I felt EXTREMELY nauseated. I could not go to sleep because my mind was just racing about work. My head is hurting and I am certain that my blood pressure is up. It is all stress. I will be glad when today and tomorrow are over with so I can relax again. Pray for me, send me some positive thoughts and energy!
