It was on Friday at school. I was in chorus class, and we had a paper to write while the substitute was here. One of the younger students started ignoring the subs scolding and was using the teachers computer. We tried to tell him to sit down, and he singled me out. I was getting angry. I told him to "STFU(in words) and sit down." and no one seemed to care. He said some more things and walked away. The next thing I knew my eyes were tearing and I couldn't stop it. After a few minuets the class noticed and proceeded with their insensitive comments that made no sense. I started crying more, and ran out of the room. It didn't stop until almost an hour later. I really don't know what set me off. Similar things have happened, but i never broke out crying like that. What happened?
I have had the same experience almost to the letter. Children/teens will get restless when something happens that is outside of their normal routine. Even if there is a substitute in the class, the chances are that this sort of thing will happen. Luckily for you there actually was a teacher in the class. In my experience there was no teacher present. My advice to you is to tell your guidance teacher, you might cal them councilors. Also, next time there is a subs teacher, just remove yourself from the room as soon as anythinglike that starts. Just don't get hung up on it, it just happened because the class was restless.
Was that kid yelling at you? A lot of people can't handle themselves if other people yell at them. Same with me sometime ago. I went berserk because of a teacher scolded me by trying to yell real hard. Normally, that doesn't bug me much. But I could to tear him apart that day. I guess what happened was because of that brat yelling at you. It happens, and it is normal. Don't worry too much about it :)
Okay, so he singled you out. I'd assume that he, somewhere on his rampage, got you somewhere mentally or emotionally. It could have been something else, but I believe that this is the most likely case. Oh, and curse words aren't very effective since it's so common. It's more potent if you taunt him....
