I assist in caring for my fiance's 94 year old gma. For background, in February she was diagnosed with CHF and Rectal Cancer. She was in the hospital a week and rehab facility for almost 2 months. She is home now and we are noticing increasing grumpiness and some confusion. she will take a nap, and wake up and ask who the kids were that she saw standing in the next room. no kids were there. I understand the tiredness, but she is just increasingly grumpy. She snaps at us for disturbing her..and then snaps if we dont talk to her enough. She is on Prozac for anxiety and I am wondering if we need to up the dosage or if this is just what we will be dealing with. the other day in her crankiness she told me to do what I wanted becuase she was dead anyway. I constantly feel like we can't do enough or we are on borrowed time. It's frustrating.
