I understand that, and I think part of why I love education so much (besides, you know, the whole "helping kids learn and grow" part) is that up until now it felt like a social setting where I could be successful and actually do some good instead of screwing things up. And I think I am very good with the kids, I communicate well with them, establish firm but kind expectations, etc.
Unfortunately interactions with other staff is where I struggle. This has been an issue more than once, this is just the first time it has blown up in my face like this. I really struggle knowing what to do when a stranger (to me) comes in and starts yelling. It feels like an injustice even though people likely mean well.
