Fun (non)fact: do you know what the acronym MATH stands for? Mental Abuse To Humans. lol
I agree tho, math can get fucking frustrating. Especially when you get away from computational math and more into proofs.
A surprising amount of mathematics is actually easy once you've learned it. Of course, once you learn the easy stuff, then you have to start tacking the deep stuff, and that gets harder.
One of my differential equations profs was explaining a new concept on the board, he did a example question and we were all like wtf

. This is at a school where most people do math contests and love math, so not your average students. He then asked us to differentiate x^2 with respect to X. Ofc we cud all do it with our eyes closed. HIs response was, "the reason you could do this, but not the other new thing, is because you've differentiated hundreds of times. So if you want to get good at this, you're going to need to do it hundreds of times". And it's true. Nobody is really bad at math. Some people jus pick it up faster. It's just a matter of practice and repetition
