Grandma is 88 years old, is demential, and diabetic and so requires four insulin shots every day to maintain her levels. The problem is that she also has severe hand tremors and cannot administer the insulin by herself. Ever since her husband died, that burden has fallen on my mother, her daughter-in-law. My father has since passed away as well so it is really only grandmother, mother, and me left in the family. I am away at graduate school.
The four insulin shots a day has wreaked havoc on mother's schedule and grandmother is mad if she doesn't come down at a certain time to give her the shots. We have gently suggested putting her in a nursing home but she refuses and says that we are leaving her to die and that it costs too much money that she can't afford. We suggest paying for a nurse to come in to give her shots and she still refuses saying that it's too costly and she doesn't trust people. We don't know what to do now.
My mother is burnt out and is unable to do what she wants (travel to see her own father, and me). As a widowed daughter-in-law, does she have any obligation to take care of her widowed mother-in-law? What would you do in our situation?
