A life review is normal as we exit middle adulthood and enter into early late adulthood.
I have a few regrets but those ships have long sailed and I can only live in the here and now and make better choices today.
My last job was also very high stress working 70+hours per week, being on call 247 and working for a company that used its employees to enable a dysfunctional system rather than being solution focused. All took a toll on my health so I finally walked away because of burnout.
My greatest concerns now is enjoying my relationships I do have, and to be present and helpful to those I was too busy for before when married to my jobs/career.
It has also been great to be able to ride again without having to return phone calls or emails midride.
