Who actually cares anyway......Dementia and my mum

Oh my life...what a journey. As off the 14th August my mum's life is unrecignisable . My sister has since passed away and my lovely mum hasn't been able to shed a tear or actually discuss her death , life . Not even really able to show emotion, asking almost daily if Sheila is alive or did she die ..
    Mum can no longer leave the house alone as it is not safe for her to do so. She has to rely on the good will of the strangers she calls family , son's and daughters namely.   I spend alot of my time sorting out mum's things , from tidying  out the house to shopping  , paying bills  and the like . I know my mum has had a couple of falls and that she has been luck not to be harmed by this , but , it has just been that , luck.
   Iv had to discuss all manner of topic with my mum. In order to prevent some future catastrophe taking place. Namely mum's death and home situation when they arise . Mum's agreed this should all be done in advance. She has no specific wishes or intentions towards any part of her demise or future care. She doesn't have any special requests or orders to partake to anyone . She has no special flower or tune. I am sure though some one will make that their duty to the detriment of all others..
