HappyFeet02 - hope things are a little better for you... have you found any solution(s) that might work for you to give you the break that you need? My Italian grandmother always said, "They always beat the horse that pulls the hardest" (i know, this is rather ghastly, but she came from a rougher world). In my own life, I've found the more I've shown I can handle, the more capable I've seemed to others, therefore the more work that gets steam shoveled my way... (ah, bipolar mania - its' a blessing and a curse!)
I hope you can assert some of your rights at work to get some reprieve.

Take care
