I've been very close to my mother pretty much all my life and have lived very close by her most of my adult life as well. When she started showing signs of dementia about three years ago, she was only 10 minutes away and I had a lot of time with her -- both helping and enjoying her company during her very slow decline.
Now she lives across the country with a sister (one I am not close to) and our contact is through occasional phone calls and letters, both of which are very hard as her dementia has increased. She can only carry a very short phone conversation, and her handwritten notes look less and less like her, and are now typically two completely repeating paragraphs. For the first time today, I cried not because I miss her -- which I do -- but because I miss the OLD her. It was very hard.
I will be visiting her in the spring, which will help somewhat, but I am struggling with this weird mourning I am feeling now.
Just wanted to put that out there in case anyone can relate or share their experience that I can learn from. (It's been a hard holiday season -- another sister who is my best friend, and whom I would typically reach out to in such a situation, attempted suicide right before Christmas. Needless to say, I've been feeling a little bit unmoored.)
Sorry to unload but I writing this was helpful.
