I tend to overreact and become rude and defensive when a situation takes an unexpected turn.
The sudden lack of control makes my brain go haywire instead of calmly trying to work around it, or just accepting that I was being overconfident/too greedy about the outcome.
It’s not too much of a problem nowadays, but when I’m feeling down the threshold is lower and it can lead to some awkward interactions that make me feel bad afterwards.
But it also taught me not to take people being rude to me as personal (when there’s no reason to).
