Karin....I am so sorry for your loss. Knowing that the end is coming very soon does very little to lessen the blow when it does finally come. The pain is very real indeed. To you and to your family and friends my deepest condolences.
When my Dad passed away a dear friend sent me this poem. I found much comfort in it and I hope you will find some comfort in it too.
I am standing upon the seashore. A ship, at my side,
spreads her white sails to the moving breeze and starts
for the blue ocean. She is an object of beauty and strength.
I stand and watch her until, at length, she hangs like a speck
of white cloud just where the sea and sky come to mingle with each other.
Then, someone at my side says, "There, she is gone"
Gone where?
Gone from my sight. That is all. She is just as large in mast,
hull and spar as she was when she left my side.
And, she is just as able to bear her load of living freight to her destined port.
Her diminished size is in me -- not in her.
And, just at the moment when someone says, "There, she is gone,"
there are other eyes watching her coming, and other voices
ready to take up the glad shout, "Here she comes!"
And that is dying...
