I Miss Talking To You

I remember it like it was yesterday, that day the doctor told me that my mom had dementia. "How could that be?" or "How could this have happened?" I kept asking myself. My mom has always been a very friendly, happy, active person. She did not smoke or drink alcohol, but still, she was stricken with this disease.
I kept asking myself several questions:
1
I Miss Talking to You
How could this happen to such a good, Godly person?
Why did God allow this to happen?
What will people who know her think when she does not recognize them?
What will people say about her?
How do I deal with this diagnosis?
Who can I talk to about my fear of losing Mom, as I know her?
Who will she become? Will she still remember me? She's a minister of the Gospel. Will she forget the Word that she knows so well?
