My Wife's struggle

Stephie's (my wife's) condition continues to degrade. She was first diagnosed with dementia/Alzheimer's disease in 2013. She was put into hospice a year later. Since then, I've been taking care of her at home, and slowly watching her degrade over time.

The periods where she is coherent grow fewer and further between. She no longer recognizes me. She think's I'm our son.

She struggles to say simple things. I would like to think that her mind knows what she's trying to say, but it gets lost in translation to what comes out of her mouth.

I'm sitting here crying, I can't help it. This is not what she wanted, to lay in a bed, existing. What compassionate deity would trap such a gentle soul in this kind of hell?
