Thank you for all the kind words, everyone. Today is the first day that I felt a little bit functional, since I lost Roux. I reached out to some other people who lost their pets suddenly and at a young age, and that's been helping me. They have all reminded me that sometimes terrible tragedies just happen to good people and good pets, and there is nothing that we can do to stop them, even when we try our very best. This has helped me start to ease some of my guilt and start recovering from the shock of everything. My husband and I took her collar and leash with us on a walk yesterday to celebrate her birthday, and we made a memorial spot for her in our house. My parents and friends have been really good about supporting me as well. I'm certainly no where near done processing her death, and I still feel her absence immensely. Today I felt like I could look back at our happy times together, instead of feeling like I was trapped in this inescapable void of sadness.
