Kev, I have also struggled to get some of my work colleagues to understand the fatigue. My boss has openly said to me “I can’t imagine what it’s like for you so I won’t attempt to!”
Paul is absolutely right to point out the difference between fatigue and tiredness. Tiredness will abate with rest.
I have decided to take the advice given to me from occupational health and my doctors and retire early.
Getting up at 5:40 a.m. and not getting home till after 6 p.m. was leaving me exhausted so I will be retiring 26/9/18.
I hope Paul‘s blog helps you get some of the message about understanding fatigue across.
Best wishes,
Ian
