Sometime I feel just like the poor old man who knows what is coming, but is completely powerless to do anything about it.
What you say is true, so make your peace with God and His world and wait with patience.
You are still lucid, can express yourself well and have this marvelous sounding board for your angst. Life IS good.
This life is a blink in time. Eternity is, well, forever. So, get ready for eternity.
What reassures me is that God loves me and wants the best for me. He doesn't give us anything we can't deal with. We do our best, usually, and leave it up to Him. If we can't trust Our Lord, we are doomed.
