Sometime you just have to move foreword. Finance, health and many other things can force this kind of change. The important thing is that you find something that will fill the void that this change will leave. A friend of mine made the transition to remote control airplanes flying/building. Must have been a good fit for him as he has been doing it 10 plus years.
Please don't be a stranger here as you have something money can't buy, experience. Good luck in what ever you do.
