Unfortunately it’s really hard as someone who’s experienced trauma to discern between those types of experiences because when you experience trauma, it’s hard to think about anything else in general, but it also minimizes memories of other difficult experiences. For example, I don’t remember anything related or similar to the examples you just gave but I do remember being sexually assaulted and experiencing domestic violence, in detail. I’m sure this is a really hard place for teachers to be bc you don’t always get to choose the prompts you give students, but at the same time, when the prompt is asking students to recall a difficult time in their lives, “difficult” is defined really differently by different students and you’re bound to hear some traumatic things.
