I have never understood this business about asking others if it is time for you to retire or if they agree that you should retire.
Who can peer into you soul and understand how you really feel? Certainly no one on this forum.
You know the answer to that question...whatever that answer is. No one else can answer it for you.
If you can afford to retire, and want to retire then make a decision. End of.
The OP asked "Anyone else been here? How did you deal mentally/emotionally with walking way from the money?"
I think that's a valid question and I'm learning a lot from the responses. I'm in the same situation.
