work is awful

I was thankful that I was kept at my job and didn't have to move location .............. but we are so short staffed and work is so manic that I think we (the ones that were left behind) have drawn the short straw..............it is a nightmare. I really don't know how much longer I can continue to work at this pace - especially with my bad leg and now a bite on my right shin - and really feeling quite awful.
