I'm really sorry for your loss. I lost my cat last January. My mom came to wake me up to tell me that she found our kitty outside of the bathroom on the floor. She had passed away. I still have trouble accepting it. I still don't have peace over it. There's a lot of guilt. I get what you mean when you say you get up and think you have to do your daily routines. I used to get up, say good morning, feed her, run errands when I had to go outside, come back and say hi, chill with her, then go to bed and repeat. When I would come home, she'd come up to greet me.

It's very hard losing a pet, but it sounds like you were a very sweet owner. Your dog isn't physically there, but I believe that your dog is with you in spirit. <3
