I had a job once doing career/stress counseling with industrially injured workers who couldn't go back to their old jobs - truck drivers and loggers and nursing home attendants with broken backs or paralyzed arms. The general approach was : what did you like and not like about your previous job? ... ok, now what did you like about it that didn't require you to lift 50lbs every 10 minutes? ... ok, what other job has that part that's left over. One of the toughest was a cop who'd gotten shot. His response was (no kidding) "What I liked was being able to push people around."

Anyway, from reading your posts and having met you briefly, I'd guess that one of the things you liked about your previous job was "understanding how software works". And apparently one of the things you didn't like was "spending more time with pixels than with people". So, we do the math: understanding - isolation = ...

Being a career/stress counselor and being a programmer are only two of the half dozen or so careers I've had in my life. Change is good (but often hard). Good luck. Don't be a PM stranger!
