"Your present job makes you..."

Tired. In one word, tired. I wake up at 5 AM to go to the Bakery at 6. This in itself is bad enough. What makes it worse is that I never go to bed early. I try to sleep around 9, but it doesn't work; I end up staring at the ceiling for half an hour. Also, by the time I've finished my 8 hour shift, I'm completely knackered (fatigued). I'm on my feet for most of the day, so my toes are sorer than any other part of my body. My work is physical and constant; I never get a chance to take a breather aside from the short breaks. When the boss isn't around, I can't bludge; there's always a deadline set, or my co-worker at my back. It's starting to get to me.
