My job makes me sick

I swear!  If I am off for a few days, I will feel absolutely fine.  Great actually.  But 2 hours at my job and I am nauseous, sore, tired - just plain blah.  I know it has to do with my feelings at the place but I don't know how to overcome it.  I hate being at work and am miserable every moment I am,or even thinking about it.  And when I leave, I need to lay down almost immediately to feel better.  That really puts a kink in my life.  It's sad to say that I lay awake at night and pray that my company will be shut down and I'll get a call that I dont' have to go in anymore.  Which isn't fair to my fellow employees that need the job (even though they are miserable too).  I count down the days until I don't have to come back.  The wedding is in 165 days, so that means 163 days of work left!  Off to  dream of my days of being a housewife.
