I am puzzled what the problem is. Did your wife and child die? leave you? Or your you just being pre-emptively sad that they might die? Statistically you are the one most likely to die first.

Consider butterflies and roses. We value them because they are evanescent.

My equivalent is a horror at watching beautiful people age (even people I don't know like celebrities and porn stars). Seeing arthritis, baldness, a creeping paunch, sagging skin seems such an unreasonable assault on such a figure of beauty. The death for me is just the final insult, and a merciful end to an often painful degradation.

You want to do reasonable things to protect them without driving them nuts, e.g. keep the car in good repair, keep the hot water heater in good repair, keep the gas in good repair. Teach your kids a protocol to keep them from being abducted voluntarily.

You will find if you talk to old people they have less and less appetite for immortality. Life is like a roller coaster ride, and they have had enough.

If worrying about things that might happen in the future becomes a major preoccupation you might read up on Ken Keyes’ second and fourth pathways.

(2) I am discovering how my consciousness-dominating addictions create my illusory version of the changing world of people and situations around me.

(4) I always remember that I have everything I need to enjoy my here and now unless I am letting my consciousness be dominated by demands and expectations based on the dead past or the imagined future.

My room mate’s father died leaving his 80 something wife behind. We worried she would wither. However, she went out dancing, found herself very popular, and soon had a new boyfriend. It is not required to pine for a lifetime when a loved one dies.

I once asked myself how long a life would be enough, how much too long? The usual 80 is really not that bad.
