This is Kawaguchi Hidetoshi. This is my humble answer to the question.
There are times when people get frustrated and say bad things... of course, there were, and even now...
It is quite difficult to control bad emotions and worries, but if the pattern has been determined to some extent, I think it is possible to avoid it by taking different actions for refreshment, rest, change of mood, etc. beforehand.
In particular, they are refraining from taking the exam, and there are times when they put up with pressure, anxiety, and various things, and stress may lead to frustration...
Also, if you lose your motivation a little and withdraw without going outside, you may end up feeling even more depressed.
If you want to feel a little refreshed, I think it would be a good idea to go to karaoke with friends, go shopping, or just take a walk.
When I was an examinee, if I wanted to change my mood, I would go to karaoke and game centers with my friends, wander around the town for a bit, and read a book leisurely at the park. Occasionally, I was able to get off at a station I'd never get off at, walk through shopping streets and back alleys, and feel refreshed somewhere.
After that, it's an increase in motivation. I think that if you envision your own future and dreams, enjoy the atmosphere of campus life by actually going to the university where you take the exam, go to the job site you want to be in the future and try to imagine yourself playing an active role there, I think it will further encourage your studies.
Anyway, this incident has already been reflected on, and they have apologized, and they also have feelings of repentance and shame, and with regrets up to this point, be careful not to repeat the same mistakes, take care of your physical health (colds and hay fever are enemies... experienced people say), and do your best towards cherry blossoms.
Also, with regard to anxiety, we have dealt with humble answers to the following questions until now, so please refer to them even when you have time.
