Hi there!
When you decide someting or take action, why to do so based on what?
Me? - I follow my guts
.
Yes... most of the time I follow it. (Sometime the word "obey" might be more suitable! 
)
This is happened to me even in work enviroment. And so far.... overall it went quite well
It is NOT meaning that when I don't feel like to go to work when I woke up and take day (or a few days) off immidiately.
What I mean is.... ACCEPT THAT FEELING.... and accept you as the person who feel so....
Then ask yourself why you don't feel like to go to work.
One by one...step by step... reveal your "TURE" feelings. 
Most of the time you find the hitting point to become feel neutral ( means no good or bad) then ask yourself :
"What you want?"
the answer is still " I don't want to go to work" THEN.... It might be the right timing for you to do so.
Your body might be tired. so as your mind too.... Remember - Your body, mind and spirit connect one to others.
And you might shut your feeling down to feel so.
Nobody can feel EXCACTLY the way you feel.
Be nice to yourself. You are the only one "YOU". 
Enjoy your day!
