Please help me understand.

My mum was told a few months ago that she had something that looked like a tuma/cancer. We all agreed that to put my mum through the agoney of a biopsy she wouldn't cope with the outcome. As my mum has many other health issues c o. p d eating was hard has she couldn't swallow. She had her pipes stretched but doctors never sent the tablets out to help keep it open so it was done again. In the end there should have been another a temp. As mum was already in hospital the doctors there would take her from the ward. The list goes on with her health but it doesn't mean i have to watch this crule and slow death.

I was told by the doctors that my mum now had full blown cancer and it had spread to her ribs and bones, she had only days to week to live so she WS sent home with end of life help. Hospital bed and oxygen. The family was told that we could have oxygen to take her out to make memories if she was up to it. We did this twice and then she was in pain. We gave her morphine 5mls oh yeah after making us wait for two days with no pain relife the meds i was give in her was for her chest. My mum got worse after only a few days but we could cope she wasn't all to gether there but we could get cuddles and she knew who we were just about. Then they Gabe her the shringe drive after me fighting for two days not to have it. The out come now is she can't move she not allowed liquid as it fills her lungs so her mouth is so dry. My my is trying to tell us something and we don't know what. Horrible then were told this could last up to two weeks. Someone has got this so wrong. My mum was deteriating i get that but not like this. What would happen if i ask them take the shringe drive out or can i get a secong apinion. This is not my mum and she looks at peace but i know she isn't.
