I am so sorry you are going through this sad time. Your mom and you will be in my prayers today. I pray that He will give you the wisdom to make a choice and be at peace with it.

Anything I'd have to offer you would only be my personal opinion. Perhaps you could ask the doctors to be more specific as to what would happen if you withdraw fluids, and if you don't. Are the fluids considered "treatment/medication"? Or are they considered "nourishment"?

Your mom may not see her remodeled home, but she will have had the knowledge you were helping her with it, and the joy of anticipating it.
