Went to see my Mum in hospital today. She's such a mess

She can barely follow a conversation, keeps falling when out of bed, and has to drink from a baby's sippy cup because her tremor is so bad. According to her notes, she has brain damage from the liver problem. I'm hoping it's reversible, but they still haven't found the cause of the liver problem so time is running out
We have a meeting with the Consultant on Mon so I'm trying to distract myself from the anxiety that she's going to die or be permanently brain damaged until then. The thought that I might never have a proper conversation like we used to have with her again is very upsetting. As is the guilt about how cross I've been with her lately
