I was trying to explain what I mean by tired to my mum a few days ago, she is of
the everyone who works is tired so just get on with it frame of mind 
I was trying to think of a better word but there isn't one, dp always says I'm like a toy that's battery has run out one minute I'm working the next I'm not.
I have hidden how unwell I've felt for the past couple if weeks but it's getting harder to, today I look ill, I'm pale and look exhausted, my eyes are black holes in my head, I know this because everyone's told me, every mum I saw at the school, dp, the Tesco delivery driver and my boss all felt the need to tell me I look tired, I don't know whether to cry with relief that I look ill enough for people to believe me or to scream with frustration that I have to get to this point before people notice.
Also why do they feel the need to comment, telling me I look tired and I'll does not help it just makes me feel even worse. my boss has arranged cover for tomorrow afternoon so I can finish early so I know I must look really unwell.
I'm trying hard not to phone in sick as its only 3 weeks till my operation then I'll be off for 2.5 weeks but it's so hard to keep pushing myself, every little thing takes more energy than I have, I sobbed whilst brushing my teeth this morning and I haven't felt like that for months. I can cope with the pain and nausea and bleeding gums and sore ears etc etc etc BUT I can not handle this bone deep, foggy, word slurring exhaustion!!!!!!!!!!
