I really feel for you. My mother had vascular dementia and after my father passed away, she would ask every day where it was. She had type 1 diabetes and we cared for her in her own home, but it is really sad and takes a massive drain on you, both emotionally and physically!
Oh no @tengolotodo, I can just imagine how difficult that must have been as living with type 1 diabetic can be quite worrying at times with the highs and lows plus having to deal with dementia is a double blow. Thank you for your good wishes!
Yeah you can only do the best you can do.
