I'm glad you found @edsutton helpful. He is often a guiding light for those of us who "just can't do it all" anymore.
This week I am finding joy in the fact that, although I am slower and maybe not as strong as when I was younger I can learn new things (like learning all the details of using our year old camper from dumping the tanks 🤢to hooking it up) and do some old things (more slowly - like unpacking from 4 months away.) As for the camper, my husband is teaching me ways to manage the tasks safely with less strength. And the unpacking/putting away/road laundry that used to take me 48 hours will likely take about 5 days.
Another joy I have learned from my dear friends is finding suitable hobbies - instead of a huge quilt, I now make smaller pieces of art. And I found out that if you can still use your hands, even a little, you can draw and paint. Even my tremors can work to my advantage - on my shakiest days I do landscapes, flowers and birds - my squiggly lines fit nature very well.
