There's a big difference between "professionalism can be part of your self-worth" and "your work is the only source of your self-worth". Second part may be unhealthy - though, frankly, we probably would miss a lot of inventions and scientific discoveries if not for people that lived for their work - but the former is completely normal. "Untangle" is such a bad word to describe it - there's nothing wrong with your work being part of who you are, being tangled into it - provided there are other threads in that tangle.
