Oh my gosh. I need help!! PLEASE?!?

Okay, today a boy in my class had a lighter out and he was screwing around with it and it scared me. I wasn’t sure what his intentions were. I dont know why he had it. So, for my safety, my friends safety, & even his, I told. Well, that was the WORST thing I could have EVER done! He got SO MAD AT ME! I was scared.. afraid. Well, the only thing my teacher did was take it from him. That was IT. He didnt take him to the office or call security. If you mess around at my school, they take you to jail. No joke. Im SO mad though. He deserved to go to jail. Anyway, my teacher went back to the board & started teaching again. While his back was turned, the boy started reaching in his pocket and was grabbing something. I could see an outline of it, It was either another lighter or a pocket knife. Lets just say he likes me & he always ask me abt my past relationships and weird things like that. He bothers me but, I’m nice to him anyways. Back to the story.. I started getting scared all over again. I have asthma & everything. I have panic attacks easily so I just started panicking! I told my teacher that I was having a panic attack so he let me go to the bathroom.. As long as our classroom person came with me. She asked me why I was so nervous bc she didnt know what happened. She wasnt in the classroom at the time. She came back like right after the drama ended. I told her that he has something else in his pocket. That he either has a lighter or a knife. Well, I guess “he” started mouthing off while I was gone because my classroom lady had to take him to the office. Whenever her and him were walking out of the door I heard her ask him what else was in his pocket, of course, I never found out. 30- 35 minutes later HE CAME BACK! NOTHING HAPPENED TO HIM! HE DIDNT GET IN TROUBLE OR ANYTHING! I’m scared that he might hurt me. Whenever he was messing around with that lighter, my trust for him was lost. Im SCARED of him. My parents are MAKING me go to school tomorrow. What should I do? I NEED help. PLEASE PLEASE PLEASE!!
