Yes, this is hard.
Unbelievably hard.
No one can even start to imagine what this is like without going through it.
I don't know what unspoken horror my wife goes through. locked in her own mind, but I know it is hard on her too. Probably harder. She finally can't recall her children's names or much about them or gets them confused when she can recall a little. It's hard and gets harder, but God didn't cause it.
The time she can most remember her children's names is when she prays at night and asks God to forgive them for not calling or coming to see her for months. So I know God helps her remember then.
I feel blessed that God chose me to be the one to care for her and has helped me all along the way.
We each have our relationship or lack thereof, with God. For me, God is who gets me through.
