Some things seem very reminiscent of two years ago...
Grandpa is not able to get out of bed, when only a couple months ago he was walking with the aid of a walker and using the bathroom.  He isn't able to swallow so can't take in food by mouth.  He can't communicate and is growing weaker by the day.
It is hard to live through this so soon after my own Dad's experience.
But the difference is I know what to expect.  
I am really thankful that my Mom and her siblings are in agreement with Grandma on the plan to keep Grandpa comfortable.  They are accepting and working through the loss.
Walter and I were hoping to have a winter vacation this year.  Just like two years ago, we planned a trip but weren't sure how Dad was doing.  God blessed us and we were able to take that trip.  Dad passed away a few days after we were back home.  It was emotionally conflicting, but we know God gave us peace and acceptance at that time.
Again, we aren't sure whether to make plans to take some time away.  While we can't leave the country, we hope to take a break in the mountains - we would only be a day's drive away should anything happen to Grandpa.
One thing I know, God will direct our steps.  He will give us wisdom to make good decisions and will make a way for our needs to be met.  He has been so faithful and good to us in the past; He will continue to guide us to make the right choices in the next while.
Lord, be with us and especially be with Grandpa as he prepares to meet You.  We trust You to do what's best for us all.  Thank You for Your love and grace in life and in death.  
In Jesus' Name, 
Amen.
