that she is raising the tension for no reason... did not go well.
Do you see how you (in this instance) actually poured gasoline on a small fire and turned it into (kaboom)?
Can I get you to reflect on this and offer a few examples that would likely be less triggering? Maybe a couple of thoughts as to "why" your new examples are less triggering.
To your question...some sort of emotional upset, which even they themselves may not be able to articulate. Or perhaps better said...the inability to "handle" an emotional upset.
What's the "theme" in my answer to your question?
Best,
