Elaine, hi
I made the same decision about the bowel cancer screening earlier this year, it was just too much to take the samples and hubby was distressed by the thought of it, so we didn't take part either. As you say, what would a positive diagnosis provide except better end of life care, and we can only hope for that anyway.
I hope your OT has arrived and agrees with you about what you need. We have an appointment booked for have to wait 4 weeks to be allocated one, hubby has forgotten how to use the toilet now too and accidents happen especially during the night, although he is very good at letting me know when I'm needed before rather than after the event!
I also hope that you get most of not all of your sitter time, I've got two hours this afternoon too, we do seem to be mirroring our experiences at the moment.
Take good care of yourself, with best wishes from Jo
