@Elawin - what a lovely girl! I'm very sorry to hear that you're furry friend has passed on. It's never easy.
Having been there (and about to be there again), all I can say is, give it whatever time it needs, but it does get better over time. When we first lost our dog Molly in 2004, I didn't think I or the wife would ever get through it. Everything reminded us of her.
Over time, though, we were able to focus less on her passing, and more on all the good memories we had of her, and now, 15 years later, even though we've raised another dog (who's still with us), we still think of Molly nearly every day, and I'm pleased to say, it's almost always with smiles.
You'll get there. You won't think you will, but you will. Time moves forward regardless, and that's a good thing. Just give yourself all of it you need, and be happy that you obviously did an excellent job providing a good home and companionship to Polly, and that you provided her a good life while here.
Peace in the meantime. Take care.
