Mathematics has its own persuasiveness. If you can't get rid of the problem, you will mix it in graduate school. If you can't stand loneliness, you will be pulled farther and farther. In the department of mathematics, compared with ordinary people, talent is not low (not to say that people who think they have talent dare not enter), and the same efforts are also very basic.

And when you learn to study, you will find students from other majors.

Don't blame me for hitting you, you should either resist these pressures and go on, otherwise your mentality above will either come in as a stepping stone or a stepping stone. Mathematics is different from all other subjects (including physics). The building of mathematics is too huge, and undergraduate mathematics is only the result of hundreds of years ago, so what you find difficult and compassionate is just a very basic thing.
