Sending him off to heaven

I feel absolutely devastated right now. My mother just called and told me that they're putting my doggy to sleep at 3 pm today. I just want to cry but I'm at work and I don't want to be a trouble to anyone. He's been sick for a while and he's just not getting better, so it's the right thing to do... but still terrible! I'm going to miss him so much... it will be so quiet.

I just want this day to be over! I'm so happy that I got to spend so much time with him at the end of this summer.
