Mike: I thought a long time before posting this. I hope things go well for you.
Speaking as one who has been through this recently. and will be going through it again soon enough, sometimes enough is enough and easy surroundings and support are the right thing. To all things there is a season. When the season is done, the leaves fall, and trying to avoid the inevitable is often not a blessing. Mind you, it's the hardest decision one will ever make.
Mike - I lost my mother a year and a half ago in similar circumstances, and I'm in the long, drawn out process of losing my dad to a dementia disease right now. I don't pray, but you and your mother are absolutely in my thoughts. You have my best possible wishes. No one can understand what you are going through, even as we go through the same thing. Each is different, special, precious. I can share, though.
