I Can't Imagine

I can't imagine what you are going through
When you no longer know what to do.
Patience for me, is what I need
To understand, care and to feed,
The failing mind of the one I hold dear.
Please don't forget me. That's what I fear.
But if that time comes, when you do
Forget my name. I will still know you.
I love you so, my dearest wife.
It pains me to see this in your life.
