Very captivating stuff, I enjoyed it, the only thing I would suggest is that you allude to the listener the inspiration of the song in a subtle manner if possible, like adding (replacing) a line to the chorus which might go something like 'No matter what the doctors say, she'll be grateful for one more day' or some such, then we can all better understand the poignancy we are dealing with here. Just a thought.

Well done.
