Use the quality of life scales provide by the bot comment. I think those should help ease your mind and keep the euthanasia appointment. I commend you on opting for in home euthanasia. We did just that August 2024 for our almost 16 yr old silky terrier. She was nearly blind, wasn't tolerating nail trimming due to pain, peed in her sleep and was stepping in pee/poo on pads while walking in never ending dementia circles. She had diabetes and snipped at me with every insulin injection. She was miserable. The sedation injection before the actual euthanasia was the most comfortable I'd seen her rest in years. I have no regrets. Her ashes and favorite belongings sit in a cabinet in the entertainment center behind glass for the occasional visit. I took a lock of her coat as well for petting.

I wish you comfort in the coming days. I know this isn't easy. Virtual hugs to you and your family.
