Great ideas above!
Olivia, depending on what your actual situation is, when I first began fading I limited my service to going on Bible studies of other people.
Meet, go, sit, come home. Easy peasy.
There is usually someone who would love to have a person go on a study at an odd hour with them (afternoons for example).
Also, I had a non Witness friend who I studied with, who quit studying but we still met for coffee and dinner occasionally. I just turned in a couple hours a month for that.
I know another lady who used a bum knee to start her back stepping away from field service. Once she realized the mileage she could get out of that bum knee it became permanently injured until she faded. At which point it was miraculously healed LOL.
I understand exactly what you mean by wanting to do this on your terms without having to answer to or be hounded by the elders.
All the best to you!
