Is he like a prof. or something? anyways, by how the way you typed that, it looks like it's just anger and frustration taking over you, considering you're tired as well, your mind tends to thinks of crazy things. Take it easy boo, dont let them occupy you. Im not really the best to say that but..lemme know.
Disclaimer:
I am not a professional nor someone who had experienced the way you are feeling right now so it is completely up to you if you take my advice or not.
Since it takes a lot of time to practice patience,I think the first thing that you should do right now is calm yourself. Sleep it off, drink coffee or tea, read manga's, or even meditate as long as it keeps you calm or makes you not think about them.
Once you have calmed down, you should think about the consequences and I think you have that covered up since you know that you will go to jail if you do that.
And once you have calmed down, confront them about what you feel if it is not a serious matter but if it is bullying then I think you should consult a guidance counselor, a teacher, or your parents. Just make sure that you let out your feelings and so that the problem will be solved.
You should keep in mind that hurting someone won't make you feel good.
Hope you get through it sis/broヾ(❀╹◡╹)ノ~
