DAE cry from confrontation?

a very recent example i experienced and got annoyed that it happens in the first place so i want to know if others experience the same and/or know what this could be connected to.

i had a driving lesson with my instructor and we were going over test routes. i drive a manual and i’ve gotten very good with the functionality of the car and seldomly stall the car, but still struggle with some road/ sign awareness. Today we were driving and while I was parked I couldn’t understand a maneuver I did, so the instructor sat there and explained it to me but I still had some discrepancy from what I know from the rules and what we did (and I was insistent on understanding exactly the WHY if I want to be a responsible driver). So I “argued” with him (not to win the argument but purely trying to find the knowledge gap I had). He even started drawing it out in paper for me. After a minute of not getting it and trying to explain to him I started to feel myself tearing up and my voice getting shaky. I hate when it happens and in such random moments of “arguing” and we weren’t really arguing and it wasn’t a personal attack what so ever. Over the years I’ve learned to remain calm (I used to have this a lot as a child as well; not getting something first try/arguing/frustration = tears. And I didn’t like crying as a child as well), but sometimes it comes out in the moments like these.

I tried to keep my composure the best I could without involuntarily breaking down in front of him (which for me is not looking at the eyes and not speaking (voice all shaky annoys me even more) and smiling through everything (a habit I’ve adopted as a teen from reading that smiling tricks your brain to think everything is fine or shit like that lol)). I could tell he picked up on this so became softer (imo) and didn’t push but kept explaining (good cause I couldn’t talk those few seconds I regained composure). We eventually reached consensus and I understood what I wasn’t getting. After that for the rest of the drive he seemed softer in his intonation and guiding (obviously it’s because of my reaction but I hate it came out that way in the first place).

So tell me if any of y’all experience same/similar moments in your life. My reactions also depend on how I’m feeling on that day and how “mentally stable” I am at that moment; so sometimes I’m more resistant to these things but today I was already frustrated with my driving mistakes.

TLDR tried to find a knowledge gap with my driving instructor and in the process of “not getting it” almost started involuntarily crying from frustration
