sorry im a bit late on this one but i have had a similar experience.Could you go part time in your job and start a business or get another job? I wouldn't pack your job in before you have another one lined up,i did it, big mistake, i did it because i thought packing the job in would make me clearer,it created a new set of problems.I remember physical workers saying that when they hit late 50's work became harder,some do work into a grand old age ,but most don't.
Im nearly 67 and eat well ,exercise etc but i get soooo tired after manual work. I'm a big fan nowadays of kindness towards myself,took me 60 odd years to get to that one!
good luck with your decision
Here comes the sun…..are you prepared?
