To be fair, the parent poster named it exactly:
crisis.
At least in English, I think it's an appropriate term. Not on the euphemism treadmill yet, thankfully. (In my native language the equivalent word has acquired the derogatory connotations of "adult tantrum", so people go for describing all sorts of things as "panic attack" instead, which ends up being imprecise. We are not an emotionally literate people.)
Asking in a non-accusatory way: could you perhaps explain what caused you to not notice that he did in fact provide a word for it? (Asking for my own mental and social health, because I have experienced difficulties with this sort of "invisible gorilla" occurrence.)
