For instance, when someone describes going to school as “traumatic,” they often simply refer to it as a negative experience. This is not to say that everyone who went to school never had a traumatic experience; however, some individuals appear to overuse the term. Another example could be considering being lightly pushed into a locker as “traumatic.”
Op… schools have mass shooter drills. So yes going to school can be traumatic especially if you are bullied or you actually end up witnessing a mass shooting yourself. I was bullied for years which made school fairly traumatizing for me. And having someone threaten to shoot up the school I went to did not help things. They were caught before they acted on that threat but it could just as easily have been another dozen dead kids.
If OP isn’t American, school shootings probably aren’t something to even consider… My thoughts go towards being treated poorly by educators more than anything. Bullying from other kids can suck, but in my anecdotal experience (outside the US) the lasting and impactful traumas stem from how teachers and staff deal with the kids.
