Oh Nell, I am thinking of and praying for you, your mother and Aunt.
And please, everyone, although it might be difficult to consider, do discuss with your loved ones and even better put into writing your wishes if you decline into a condition like this. My sister and I have both signed enduring powers of attorney with the stipulation that we are not to be kept alive if there is no medical hope. However my brother-in-law will not even think about it.
