Hey im hoping for some guidance or clarity i guess?

So my mum has end stage liver cancer its all been such a whirl wind of struggles and emotions for us all. she met with her consultant in august who told her she only has Two months left to live,,,,,, here we are in november, im grateful for every extra day!!! 

im worried she is now entering maybe the last days now. she is up and walking but she sleeps most of the day tends to just fall asleep even stood up. food and drink is limited she seems very weak and tired. shes been struggling with her breathing and it only seems to be getting worse. shes been getting confused during the nights allot. shes woke up laid out her cloths for the next day at like 3am went to the bathroom came back to bed and cant remember doing any of it. shes awoke searching the bedroom for her work jacket telling my dad she cant find it... she hasnt worked in years now.  just dot know how to feel. i just want to be prepeared so i can be there with her as i dont live close by and have children i would need caring for.

i would really appreciate any advice.... im struggling to sleep
