I think my post got deleted by accident—
Here it is- I’m so sorry that this is happening. Whether the shooting actually does happen or not, it sounds terrifying and I really wish you all the best. I think you made the right decision staying home just in case, because lessons are not worth your life. Maybe make sure that your friends and other people know about it. I wish you all the best. I hope this is nothing more than rumours.
Just spread the word amongst the school and stay as safe as you can 
And as an addition, if u wanna PM me about it or something, feel free
