Duff, 57, left Feb. 21 to go to a Benson drugstore. She never came back.
More than anything, her family is concerned about Duff's medical condition. She needs medication for her diabetes and dialysis treatments three times a week.
Her three children and eight grandchildren want her back at home. Her friend, Mary Williams, had a special message for Duff.
"Please contact the family, if you are able," she said. "We really miss you. We hope you're OK."
