End stage liver cancer: Losing my mam

Hello im not sure why im here? maybe to chat with others going through the same as me. My mother has Liver cancer we beleive at this point it has spread to lungs and maybe other organs. she was given 2 months to live in august but we are so thankful to still have her here today. I'm struggling to cope with the thought of losing her. Her symptoms are progressing at a faster rate now, i dont live near by her so i visit a few times a month. she doesent seem to eat or drink when im there and thats worrying, she falls asleep all of the time. her legs have started to swell and shes very itchy. pain meds dont seem to be taking the pain away anymore ( Dr keeps increasing morphine but pain is progressing quickly) shes started to get pain in her arm anyone know why this is? im just not ready to loose her. our relationship is a bit strained unfortunatley. but she seems less intereseted to talk these days too.

any advice would be amazing.
