Am I playing villain?

I have to go to school tmrw and I rlly don't want see my friend there bc I've been having lots of things in my head. She pissed me off so bad yesterday that I ended up unclean again. Should I brush it off and act like nothings wrong tmrw or no? Idk what to do. I don't want to loose her,I've been attached to her like a pet dog for so long. Idk how I should act abt what she did. Also would it sound like I'm blaming her if I accuse her of what she did to piss me off? I need answer ASAP before tmrw!
