If you are really tired with work, depending on your job can you not go on a sabbatical, to really find out if it’s just a long holiday you need or you are really at the stage in your life to call it a day.
I have done the above, and have taken the sabbatical then went back to work and handed my notice in at 62 and have never looked back.
Good luck and enjoy life, like a lot of people on this forum we are the wrong side of 50.
I could take a sabbatical but i don't need to to know Im tired of working, still looking into it but Im resigned to continuinjg working until 60 now quite honestly.
