My big dog passed away this morning

Thank you everyone. Im so lost today. I adopted him almost 3 years ago I guess now. He has been my constant companion since then. He comes to work with me (in my office) he sleeps with me. When I have panic attacks or when he does, we snuggle together. When the thunderstorms send him into a quivering mass of tremors, I snuggle him and rubbed on his torn ear. His torn ear was my worry stone. He has done so much for me with my anxiety and now he's just gone. I hate that he was there instead of with me but I do know it was better he was there. I am at work but his bed is empty. The cats are still circling. They know. His being gone hits so hard because of what he did for me in the anxiety department. I doubt there will be another one. I had been saying for a while now that if anything happens to him no more dogs. Same if anything happens to my cats..no more. I thought I had a few more years though. Doesn't that just figure. I should know that better than anyone, nothing is for sure. Its been a really rough week. He helped me through two panic attacks on Tuesday before he started seizing and then in his last minutes I wasn't there for him Granted nobody could predict thats what was going to happen but still. A small bit of guilt, probably normal. Anyway Im rambling. Thank you all again for your kind words.
