I have that dread in bucket loads.
But it's pavlovs dog with me, I'm come close to death a few times ( I actually did stop breathing this year and ended up in ICU). But I am only just 50 and I have young children...I also wasted much of my life being controlled by a religion and a god who never existed.
I finally come to the realization religion plays on this fear and uses it to control people. Its absolutely true.
People were more religious when they are poor and or live in precarious environments and death comes at any time.
The young of the 1st world don't fear death as it's so far away from their every day experience.The elderly become tired, they reach their peace when they know death is inevitable. Being a nurse I have seen the fear of death is so many eyes.
I have some older family members who used to tease me for being religious. Now, in their early 70s they start attending church. Hypocrites. The older I get the more of an atheist I become....when I see how unfair the world is. I defy any GOD who has allowed this to happen to judge ME.
