gosh I am so so tired today I haven't done anything either, my tummy's a bit sore too and I had a wee touch of the runs earlier, feel a bit hungry now but just want to sleep.
Everythings totally draining isn't it. When I'm at home I even put off going to the loo as it involves getting up and walking! You should have a quick disco nap and then eat. X
I totally get you on the going to the toilet as I seem to be running so much it's such an effort to dragt myself up and down the stairs all the time
