Oh am so sorry to hear that..how often do u see her?15 years that's amazing. Your mom must be awesome and i bet your Nana looks for her everyday. Even with dementia, they remember emotions that they see and forget everything else. Renal failure, how is she with that? She have a lot going oh man.I wish both of them well.
My friends warned me to have "me" times incase i get burnt out.
They're our moms but we need to be healthy too to look after them.
