I don't know what to major in college?

It's not that hard to get a high school teaching job. It's not really easy, but a lot easier than getting a job as a research scientist. You'd need a PhD in astrophysics or marine bio to really do anything in either of those fields, and many people finish the PhD and then can't get a job in the field because there are so few jobs. If you're not good at math or science, you aren't going to be a research scientist. High school English teacher was the most reasonable of those options.
