Funny, but I just hear Candidlynuts say my words.
I too had to see a therapist a few years back about coming to grips with mortality. Like you Candidilynuts I had been brought up to believe that I would never die. I went on to see a psychiatrist for another six months before things straightened out.
Now like all the others I just hope for good things and accept that inevitably death comes to us all so we should live each day as a precious gift and enjoy every moment with the ones we love.
But, and it's a BIG but, I believe that it will be all right. I"m not able to give any evidence of this or even explain what it means but I believe strongly that whatever happens in the end, it will be nothing to fear.
I"ve had a life time of being afraid of Armageddon and 'the end of the system', now I don't 'fear' any more.
I wish I could quote you some solid evidence but I can't. In the end it appears that good does conquer evil,and what goes around comes around. Divine justice, maybe.
