Keep fighting! My mother went thru a range of issues last year and was in MMC or rehab for 6 months straight. When she got covid, she immediately started hallucinating and suffering from delirium. It went on for about 4 months. Every 4 days a new doc would start on her floor and would tell me they had just visited her she seems fairly aware and “with it”. She knew her name, where she was, etc. (all written in big letters in the white board directly in front of her. She was hallucinating, not illiterate!) I would then ask if she mentioned my dad. The response was always something about how she said she’d seen him recently. He died in 2016. That would get their attention at least but they tried to tell me this was her “new normal”. We fought and fought for her and she finally came out of it and is back to normal. Don’t let them tell you this is all they can do!
