Move her to a better location now. I don't know where she lives, but that is a factor. Get her someplace where she can depend on public transit for everything and not miss the car. Many downtowns have great transit, but there is no convient grocery store, or if there is it is the high priced luxury store. Many transit systems don't run on Sunday, so she won't be able to get to chruch. (What other activities doea she do that are not 9-5 that transit does well?)

If you have to move her far, look for blind support in the area. People and friends in her new location are important to making it feel like home. Make sure you can visit, and also other family.

Other have addressed reading better than I could so i'm giving a different food for thought.
