Parents' anxiety about you is also worried that you are not far enough, because the small setbacks in front of you have delayed your development. So if you want to reassure your parents, you must look them straight in the eye, then firmly say how to make yourself live independently in society after dropping out of school, and then carry out your plan in a down-to-earth way, so that they can see from your actions that you can support yourself well without going to school, and you will have to bear the regret in the future, because you chose it yourself at the beginning, and you yourself said that you have reached the age of legal adulthood and can be independent.
Besides, you don't want to go to school because you have problems with the teacher? Teachers become a thing of the past after you graduate, and many students can't remember who their former teachers were. Teachers educate students not only to earn money, but also to educate people. If you succeed, he won't get any direct benefits, you can't learn, and he has no special loss. The reason why the teacher criticizes you is mainly to make you succeed. Why do you still hate teachers?
