I get uncomfortable with loud noises, but only when they start in a silent room.

Hello, I really want to kinda of vent about a strange problem I've come across

So, it all started friday when we had a history test. (For some context my class is REALLY loud and this kind of get on my nerves)

The teacher handed us the test and we start doing it. I did in fact study BUT only one of the 3 things I've should and this thing had literally ONE question about it. So basically I was cooked and trying to focus the best so I could remain alive when the results came out.

The class was silent and there I was trying to remain calm while praying for however god attended first. When I hear a "Tche tche" (a idiot joke that I still don't understand fully) and god it gave me one of the most UNCOMFORTABLE feelings of my fucking life. It was horrible, principally when the others "class clowns™ started to do the same thing. The room who once was a silent capsule now was erupting in loud voices and I was in HELL. I started shaking slightly from all the loud noise. I almost begged the teacher to make them shut the fuck up.

It happened more FOUR times and god it was horrible. Even when I had finished it still bothered me SO MUCH. This is only one example but it was not the first time.

Now, for the strange part. For some reason when I enter a loud space I don't feel uncomfortable with the noise. Like, if I enter the classroom when it's already loud I'm not bothered.

In conclusion, you may say it was because of the test but no. It's in any situation. If I am in a silent ambient and it start to get loud I get uncomfortable even if it's my own house.

This was it! Btw I love you all, thanks for hearing me yapping.
