Wow - you have a lawnmower!
Sorry Dizzydixies to hear about your mum. My mum died from advanced breast cancer almost 4 years ago (10 April), and one of the most frustrating things was the distance between us. She was in Leeds, I'm in London.
There was obviously a geographic restriction but also, because we weren't with her all the time, we had to think very carefully about visiting because of introducing germs/risk of infection during her chemo.
And during all her illness/treatment, she insisted on treating me as a child, rather than an equal and really telling me what was going on. This despite the fact that we were very, very close. I know it was because she didn't want to upset/hurt me, but I so wish she had really told me what was going on, and confided how she was feeling, etc.
I can't offer you any practical help but just wanted to give you some emotional support. I wish I had been able to talk to her doctors. Unfortunately, my mum died very suddenly from an infection contracted during her first bout of her second lot of chemotherapy.
So - if I were you - I'd be doing whatever I could to talk to your mum's doctors.
Good luck.
