I worked at a major regional bank in Pittsburgh for over four years before I had to call it quits at the age of 30. I was having chest pains, was 40 pounds overweight and at the end of my physical and emotional rope. I quit five months ago, completely of my own volition and for no other reason than I honestly believed I was dying. Walking away from a high-paying job with no college education in a depressed economy seems like the stupidest thing I could have done, but it saved my life. The ramifications have been largely positive, and my only regret is that I didn't make this change sooner.
