Hell, Welcome to Healing Well.
I am Kitt. I am so sorry your dealing with this difficult problem with your Grandmother. I am wondering if a big intervention would not scare your Grandmother more then if a couple of her closet children sat and talked with her.
I would guess the goal is to get her into the physicians office to rule out any other disorder that may be going on.
There are members on here that are experts and will have a lot of good information for you.
Your Grandmother is lucky to have such a caring and loving granddaughter.
