Dawn, those first days are the worst. The absolute worst. There is a huge gaping hole in your heart, and you don't think you'll ever be able to fill it. The dog dish sends you into sobs. A clump of hair in the corner sends you into sobs. That muddy footprint sends you into sobs. I've been there, done that, and can still cry about it 5 years later. I know it's trite, but it does get better. Each day is a little easier than the previous one. Then, there will be one day that you make it through without crying. But, that doesn't mean that 5 years later you can't think about your precious girl and not start crying again, having that feeling as fresh as it was the day it happened. Every time someone posts about losing their pet, I always start crying because I remember the day it happened to me.
Deep in my heart, I know you did the right thing and Annie was waiting for you to be with her at the end. I understand why you didn't visit her because I would have done the same thing.
About two years after my Dugan died, we broke down and got another dog. Reilly is a crazy terrier, so different from my cocker, but he's a love. Dugan will always be my "first born," but Reilly is a great "third born."
It's obvious how much Annie meant to your entire family. Cherish those memories and dig out the pictures you have and tell stories about her. Hopefully she will come to you in a dream soon to let you know that she's okay and out of pain and waiting for the day that you can be together again.
