A warm welcome to the board from sunny Scotland.
I can sympathise with your work situation as I found myself in the same place many years ago. In the end, I took the money and ran. It was the best career move that I ever made.
I can only suggest that you look on this as an opportunity - have a complete change, move, do the things you want to do etc.. At 60, that's a good age to retire. Don't make a plan to just survive - make a plan to enjoy life. No, don't even make a plan - just do it.
I am 60 yrs old working full time, feeling beat down. Family and friends continue to disappoint. Work place trying to weed out the higher salary workers. Trying to formulate a survival plan for the next 15 yrs. Feeling super defeated.
