Oh my gosh! You poor dear.
I feel like she's a part of our family because of all you've shared with us about her.
I am praying for you...that God will provide a replacement driver...that He will direct you to get all of the "stuff" done...that you will feel His arms of comfort around you.
I'm sure your mom is now dancing in Heaven, probably talking up a storm.
Please know that I hurt for you and will keep your family in my prayers.
