I, too, am saddened by your story. I must admit after witnessing many people "cross over" (I cared for both my grandparents on home hospice and I was an EMT for many years), it does not appear that you will need to know what to expect. The body has a kind way of just shtiing down, system by system, and then the LORD comes for you and you are at peace.
Do have home hospice, and do allow your family to be with you. Some family members cannot handle it, and they know who they are, but it means much to those of us who remain, to know that we were "with them in the end" and to see the gentleness of it all.
I am happy that you have come to terms with your mortality, and have such an inspirational faith. Your loved ones are there, and are waiting to celebrate GOD's love with you. I know heaven is a wonderful place, because my grandparents are there and they were the two finest people I have ever known.
Make memories in your final days, and say all your "goodbyes". May your passing be just the beginning of eternal life.
Blessings~
