Unplanned mess

My grandma was supposed to have surgery yesterday but she ended up not being able to go in because her lung function wasn’t where they wanted it. They cancelled the surgery and admitted her to the hospital. What’s upsetting is she can’t have any visitors. Another worrying thing was while I was there yesterday I saw them move a potential covid patient in across the hall. It’s a super scary thing. So I’m a bit worried about my grandma being by herself and worried about her condition. I haven’t heard anything about her condition. Has anyone else had an experience like this?
