School shooter situation

Yesterday, my friend’s EX said he wanted to shoot up our school because she doesn’t have his stuff(juul charger..childish af) and then sent her a picture of him holding the gun. She told a teacher and I told an admin, and she said it was taken care of, but I don’t feel like I should go to school tomorrow? Thoughts,? I think another friend of mine told police too. I can’t sleep at this point
