That sucks, Dex, I'll send some prayers your way. Both my grandparents fell down and broke their hips, and I had to watch/care for both of them while they wilted away, neither walked again after the falls. I really hope that's not the case for your mum (both my GPs were in their 80's, which definitely contributed to it), but hip injuries in elderly people are serious matters. Can't imagine having to deal with that in the middle of a pandemic, AND knowing the hospitals can't even care for you own mother properly because they're filled with selfish, ignorant a-holes.
Best of luck to you and the family.
