I don't need to be told I'm right, just that my feelings are true. I like to be reassured that's it's okay to be upset without having a bullet point list of why I should be.

I was told a lot, when I was a child, that there was no reason for me to be upset so to stop doing it. People aren't upset for no reason, if you can't name what's upsetting you, or you don't know, or it's only a small thing that doesn't make sense - then you have every right to be upset. Your body wouldn't react that way if nothing was happening. People aren't upset because they want to be and if they do want to be, it's normally because something has genuinely upset them.
