This might be a naïve idea and you didn't ask for any advice, but have you considered doing free/reduced cost work for children or the impoverished? I'm sure you'd face a similar range of responses, but that last line - "no good deed" - made me wonder if using your considerable skills for a bit of charity work might help with the burnout.

Side note: I've had to prepay for appliances and night guards in the past when the cost exceeded some threshold - the latter wound up being supremely disappointing considering it was ~$600 and broke within a fortnight, but I didn't bother complaining to the dentist since the staff would just have to argue with the fab.
