to be showing up like this

This week was terrible and sad and frustrating. My wonderful old dog may or may not be with us at this present moment - my mom said it was time to Make The Decision, but I didn't want to because I'd keep her here forever, so then she asked if I wanted to know when "it" happened, and I said no. Pretty much this is the worst thing that could be happening right now. And one of my math classes is driving me bananas, so I talked with the Vice Principal about it on Friday and he said that I should just send the ringleaders to him, but I wanted to handle it by myself. Now I feel like I can't manage my own classroom. I've been listening to the song "Blood Bank" by Bon Iver over and over again for a few days, and I wonder if maybe I should replace it with a more overtly cheerful song to get me out of the blues.
