I am happy you have a daughter to help you. It isn't always old age - I took over my Mom & Dad's checkbook balancing at 14, and doing their taxes at 24. I was just better with numbers & forms.

But nobody could fix things like my Dad, or bake like Mom. Her problem as she got older was forgetting steps when baking - she solved that by doing it with granddaughters. Now the 4 who worked with her often are great bakers!
I'm much younger than you, but I hire my windows done too - it requires climbing ladders, not a good idea for me. It is wonderful to figure out how to get things done as we get older.

Sometimes financial things can get confused ….Maybe it might have been better to line up the work for when she was around….less stressful too having someone else around…I always ask for a written bill and description of work done…and try to pay by chk. And write down the chk number and date on my copy of the bill…signed and dated..Maybe someone you trust like from your church or your bank could help. For work around the house I ask my son or a knowledgeable friend to vet what is going to be done and whether the price quoted is reasonable and only pay once the work is completed. If the worker complains about this I plead “old age” and ask them to come back later when my son is around and offer them a coffee. The main thing is not to be rushed or pressured into anything. I hope this is helpful. Every situation is different. Take care and be well

I'm surprised about side effects of some meds - ie causes confusion etc.
Then we know that Chemo Brain is real - Hope you don't have experience with that.
Arecept works well.
Also, good to study Mindfulness.
