I feel for you ~
I had lumbar surgery & had a less than empathetic husband who left me alone 8 or more hours a day! Had to walk tiny steps with a walker just to use the rest room very carefully.
That husband is now an EX, because he said “he didn’t sign up to take care of a disabled person” so I was alone as well. so I feel your pain.
We can send messages back & forth on here or if there’s a way to talk by email or something. I’d be happy to help
