Hi @HavanaS ,
Sorry to read about the difficult situation you are. It is heart melting to read how dearly and proudly you are caring your mum, definitely she is lucky to have you.
As you said hospital is not a good place unless otherwise needed. Hopefully as Tot said after your calls on Monday will be able to sort things out for her. If thinking about keeping her comfortable make sure they are arranging pain management and not stopping parkinsons medications. You 're doing your best and I would say you are lucky to get the chance to take care of your mum. Remember to support dad with emotions as during these stages people have the tendency to hide their emotions.
Thinking of you all. Take care.
Tinku.
