I can understand both sides and of course if there is some specialized treatment she would be in the best place. I did hospital car volunteer driving for over 10 years 3 days a week, so have some knowledge of this sort of thing. My only suggestion that may help a little is are you able to contact someone like the Rotary Club or something like friends of the hospital sort of thing, where they may run a scheme to be able to take people to visit for the cost of the fuel. alternatively - whilst of course understanding how busy people will be at this time - if you have friends or perhaps are members of some clubs you may have people who again would be prepared to take you to the hospital for the cost of the fuel to go there? Quite separately from doing the ambulance car scheme I took a few people over the years , who all lived alone with no local relatives, to various things , usually to visit someone of importance to them, but once took a lady who for medical reasons , could no longer drive, and longed to see the sea and there was no public transport that would have given her a reasonable day. So I picked her up from her house, took her to the coast and she did whatever she wanted to do for the day. She paid for the fuel, as unfortunately I do not have the resources to be able to give that to her but was very happy to give my time, so perhaps if you look around you may have someone who could help you in this way. I wish you the best of luck and that they will not be in hospital for long
