I'm very sorry to hear this. My dad is dealing with a very fast moving dementia and I know how hard it is.
You have my sympathys. We kept Mom at home until we just couldn't deal anymore. My wife was undergoing cancer treatments at the sametime Mom was spiraling down - not a good time for me.Wife is now 3.5 years past treatments, and we got Mom into the facility just as the wife was finishing up.
On that note - I'd like to thank all of you for being there for me.
