I'm so very sorry for your loss. I'm going through the exact same thing having had to put my dog to sleep 2 weeks ago. Even though he was old and it was something I thought I was prepared for, it was still devastating. I still cry pretty much every day, and I miss him SOOOO much.

So many of us know how you feel, hugs to you, and take care of yourself. And you can smile later, it's okay to cry right now.
