I'm so sorry for how you are feeling now. It's really the most heart-sickening feeling and the reason it took me so very long to accept another dog after Brogan passed.
I hope I don't offend anyone by saying this, but I found losing my dogs harder than losing my own mother. They were with me 24/7 and especially in the case of Brogan, he was like my right arm. I didn't even know how to walk without him right there by my side. So you're missing them terribly, plus re-learning to do all the things you did with them, now without them. And of course the assistance dog thing doesn't really matter in that context, as you mention these daily things, moment by moment - like driving in the car or watching TV - and Holly is missing.
After a few days of silence - because I used to talk to Brogan all the time when he was alive - I started talking to him again. 7 years later, I STILL talk to him. Maybe in certain circles that would make me seem completely crazy, though I know no one here would think that. I don't care in any case, because it helped me enormously to believe - as I do believe - that he's still with me.
I hope you and Ruth find your own way to ease your pain, whatever works for you.
