All I know is....Terri is one strong individual. When she finally departs this earth, and is finally granted peace, she will shine the brighter in Heaven for all her sufferings.
She is like Andersen's Little Mermaid, whose spirit ascended from the foam and kissed both the Prince who had betrayed her and his new bride, which she had hoped to be, and forgave all. The "daughters of the air" are waiting to take her away. (Don't know what I'm talking about? Find a copy of the origional fairy tale, the REAL version, which Disney massacred. You will weep through the last 5 pages.)
A silent, smiling, small army of angels is hovering over the bed and around that hospice, waiting, waiting, to take her and lead her up and away to her Heavenly reward. They will say, Be at peace. Your suffering is over, you are in grace. Let all the murmering cease, let this be your eternal release. And she will ascend, away and above all the the lamentations and the sorrows of this divided Earth, with nothing but a gentle smile for all of us left in this Vale of Tears. She will pass through the Light and the Grey Rain Curtain will be turned back, and she will hear a sweet singing coming over the water. (Tolkien's words, that last, not mine.) And when she stands before the Throne, young and beautiful again, I have no doubt that the Master Himself might even descend and envelop her in His arms. And He will say: "Welcome Home at last. It is not for you to right the wrongs. It is not for you, to fault them. Here is your rest. Be at peace."
