Update:
The doctor has confirmed that she mentally passed away this morning, around 5:00 A.M., which is shortly before I created this thread.
Today was the day that she was set to go home after battling pneumonia for two weeks in the hospital.
Early this morning she had a hemmorage (sp) in her brain. Brain activity has since reduced to absolutely nothing. The only thing keeping rigor mortis from taking over is the breathing tube and the medicines. She is dead. Perhaps as soon as tonight, what remains of her body will simply stop reacting to the medicine, and her heartbeat and blood pressure, both of which are in constant fluctuation due to their artificial nature, will continue to decline until it stops entirely.
I am sorry to say that the traditional sacraments could not be administered. Nevertheless, my grandmother lived a very Catholic life and I believe that this is one of the many cases where God may provide for a soul even if He did not grant it the grace, for whatever reasons, of learning about Tradition. She was illiterate and had many, many other tribulations to worry about. Towards the end of her life I took her back to the Latin Mass for the first time since Vatican II. She was very devoted to it, although due to the infrequency of the times we could attend, she never got the point of going exclusively.
The last two years of her life have been extremely fruitful for her spiritually. She has prayed the Rosary almost daily, and has only refrained from doing so due to illness. Before her death, I would read to her a chapter from Preparation for Death by Saint Alphonsus (her favorite book, and the only one she would listen to) almost every night.
May she rest in peace.
P.S.
There have been people praying for her all day today. The Sorrowful Mysteries have been prayed aloud for her, just in case she could hear, at least ten times today.
