I am so sorry to hear of your sudden and unexpected loss. Believe me, I know how difficult it is and, while none of us quite knows exactly what you are going through, please understand that many of us have been through similar situations and definitely understand the level of your grief.
I wish I could tell you it was easy and that soon you'll forget how difficult it is, but a loss is a loss. What I can share with you is how wonderfully supportive this group of dog lovers is and that there is almost ALWAYS someone checking in and available to lend a sympathetic ear. No one will get tired of hearing about how wonderful Seamus was, how much you miss him or how much you hurt.
So, feel free to let it all out. And if you need to, let it all out again. We're here and we understand and we share your loss.
Jeanne
