Found this on Quora, in part;

Many don’t, for a variety of reasons.  It’s irreversible, so it’s literally a last resort.  For some who think that life isn’t worth living, they’ll find that there is a reason to live before they reach the last resort.  Others never reach the last resort because it’s painful.  Some find sufficient cause to live in those who would be hurt by their death.  Some observe that death will come anyway, eventually. Still others are simply socially conditioned, through religion or other social cues, that it’s unacceptable, and are afraid there may be consequences.

Kind of where I am right now.  I told my daughter before she left that I didn’t think I’d see her again in this lifetime.  I’m still holding out hope otherwise.  Same for my youngest son though his disappearance and refusal to communicate with me was unexpected.

Then there are the individuals I owe in some way, my customers who’ve stayed with me through all this, and my wife though sometimes I’m not sure how she feels about me.

Then there is the commandment, “Thou shall not kill.”, and I’m assuming that includes myself.
