This is how it was for me too. I sacrificed my family, health and personal life for years. Then COVID hit and I found out that the company did not prioritize me in the same way that I did them. I crafted my exit plan then and was retired within a few years.
It took me most of a year to relieve my body of the work stress and loosen my joints that were in a permanent state of hunched over a computer.
Now in my second year of retirement, I have started going to the gym and taking classes. There was never time for that before. There was always a crisis.
