I was a funeral director. Left the industry in 2010 due to PTSD. Gave up my licence and never looked back. The mental health toll on the profession is a real thing given the highly emotional work, low pay, difficult working conditions and corporate influences on the industry.
I worked with 3 funeral directors who took their lives. Anyone in the industry is well acquainted with suicide, yet its a topic we avoid talking about. Still, I salute anyone who is still in the industry and those of us who have done it have a special bond and I would drop everything to help another funeral director if I knew they were in trouble (despite being out of the industry).
Unless you have done the job you will never understand the job and you are probably better off not understanding.
