Have you tried keeping your attendance or grade book in a TRI fold binder? you could keep your list inside the first cover so you see it every time you open it.
They have them on Amazon if you want to see what it looks like, just search ” tri fold 3 ring binder ”
Also take a few deep breaths and try focusing on something positive, and not play the issue over in your mind, I have a hard time doing it myself, but it does work.
And I also use a glitter bottle when I’m upset, they’re petty easy to make.
