Hi Bettyanne:
It sounds like your mother is one of those compulsively busy PD people, who goes from one distraction to another, just so she doesn't have to be left alone with her thoughts.
If you don't pick up, she'll dial the next person on her "distraction list."
She'll find someone to listen, and keep her going.
I'm sorry you feel guilty, but I really do think she'll be fine if you cut way back on the phonecalls.
You just need to be prepared to distract her with segues, and stories when she asks you why you didn't answer.
........"And then this big CAT, it was as big as a bear cub, comes barrelling through the door when I brought the groceries in. Ya. It was a shock! And then, it got lodged behind that big piece of furniture I can't move by myself. And then, I had to get a broomstick, and gently prod it out. And then..... Oh look at the time, I have to go to my new psychic reading book club, and I'll give you an update when we talk again."
Imagine the stories you'll have for her.
When you're not so busy; )
