I would give half of the money to my parents or take them finally to a health check, knowing full well that I already have money for any treatment. And the rest would be spent on achieving my life plans or goals.

I would change the presentation of information in textbooks, since information is often incomprehensible to students, even to their parents. Sometimes only a professional in this field can explain what is there and then without looking at the textbooks. Another – mode of study is not suitable for everyone, especially for those who start working at an early age, it would be good to add a flexible schedule with an online connection to the lessons.
I would add psychologists to all schools.
There is also a problem in general education, since now many people prepare for exams for years and after that they cannot even pass them. The level of what we are taught and what is required is completely different.

It is incomprehensible to me that people are being bullied because of this. At first, I would try to somehow solve this problem myself by helping the victim and would insist that the victim not give others such an attitude towards herself. If the situation has not improved after all this, then I would have already insisted that the director resolve this issue.
