Why is Geometry so hard?

I've found myself focusing a lot more on my grades the past two weeks, considering the fact that the year's about to end and my ego won't let me finish with my grades being worse than everybody's, so I have been staying up late at night doing homework and not doing anything the rest of the week becuase its all done. During this i have realized that the thing screwing me over is geometry, the subject is hard for no reason, and my teacher only makes it worse; She will never actually help you and will only repeat the question to you that youre having a problem with, and its like everytime i hear her voice I want to fall asleep, although my grades aren't that bad, why would I ever need to use trig ratios in my life? It makes no sense and schools should teach things that are actually useful to students, like filling out a tax form, because alot of students get out of high school not knowing what a tax form is, or how to fill it out, or how to open up a bank account or build credit. This drives many people from our generation to go into adulthood clueless, and go through financial hardships just because they weren't taught when they didn't have to do adult things. Anyways i hate math and my math teacher should be replaced and geometry sucks
