You know, even though I went through the same thing with my dog, Bruno (he was also fifteen, and, my best friend), I can't really give you any advice. Everyone moves on in a different way, everyone heals differently. You will never truly get over a loss such as what you're experiencing. But, I think, for most people, it does get easier as time goes by. It's just a matter of grieving when you're supposed to grieve, and, letting go when it's right for you. I can look back at photos and videos of Bruno, now, without breaking down. But, it's been two years. That's not to say I don't still wish he was here with me. And, it's not to say that I don't still wonder if I did everything I could have for him while he was alive. Because I do. I have moved on, and, you will, too, when the time is right. But, I will never get over that boy. He was too much a part of my life, my soul, my breath, and, he always will be. Anyway, I am sorry this is so long, I was feeling sentimental. I hope Bruno was there at the Rainbow Bridge to say hi to your girl.
