Thanks everyone. Today, it was the talk of the school.
Everything was normal today, well, for the most part. (we were all insane because it's the last day before spring break lol) and they only had one bathroom open (that's where they kept finding the notes) and only one person could go in at a time..etc. They won't keep it up forever, but it'll help for a while of course.
A bunch of people (myself included) were a little apprehensive about going to school today, but all is well.
