I moved to Indiana from PA in March to help my Grandparents. My Grandfather is completely blind, for the most part, immobile, and on home manual dialysis 4 times a day. My Grandmother has diabetes, but it is under control. Her big problem is some kind of mental illness or dementia. She curses, she sings weird made up songs all day, mostly aimed at me, to make me feel guilty about something, she cries and throws tantrums constantly, but she has a routine and does the things she needs to do on a daily basis. I work, and since my Grandmother is able bodied and her Dr has not mentioned dementia when she went to see him (I asked him if he saw signs of it), I thought it must be okay for me to go to work, however, I am no longer so sure. I work close to home, and my Grandmother knows she can call me at any time, and my boss knows the situation and is very understanding, so that's a plus. How will I know when I need to bring someone in to help in my absence?
