I'm feeling pretty nervous about asking a question on this website, to be honest. What responses will I get? Will people understand my question, or just mock my post? Well, here goes.

Similar to how Quasimodo the hunchback of Notre-Dame became deaf as a result of ringing the bells, does shouting at children mentally damage them?

When I was in my first year of junior school, I liked my teacher, who shall remain anonymous for the sake of personal privacy. She was usually soft-spoken and would sometimes raise her voice, but not to the point of shouting; she knew how to keep a class in order without needing to yell. We must have ticked her off many times, seeing as how we were seven-year-olds who disliked being repressed by rules and regulations, but I don't remember her shouting at us that year.

In my final year of junior school, the same teacher switched classes and thankfully taught the class next door to ours. I say thankfully because she had changed for the worse, at least in my opinion. She had a tendency to shriek and scream at somebody if they did something wrong. We did maths with her, which didn't make things any better for me. As this teacher's shouting continued with no signs of stopping, I eventually lost all faith in her and disliked her intensely. I bottled my emotions at her yelling all year until—when she shouted at the top of her lungs at two girls for leaving the classroom without asking for permission—I couldn't take any more, and broke into tears.

The reason why I ask this question is because ever since that year, I've been much more emotionally sensitive and fragile than I was before. Shouting, being made fun of, and negative comments/feedback reduces me to tears. I know I sound like an overgrown five-year-old and you're probably all laughing at me, and looking back at my eleven-year-old self and some of the stupid and disobedient things I did back then, I don't blame you. Still, I believe this teacher's shouting has mentally damaged me, because I'm seventeen now and I'm still emotionally sensitive to the above when I was able to deal with them before that year. Of course, I may be completely wrong about all this.
