i hate math

in middle school, i was really good at math. i could even say that i enjoyed math lessons (except the homework part, i still hate homework). it wasn't until i got into high school that i started to struggle with math, i didn't understand anything at all. now, in my junior year of high school, i still don't get most of the stuff that's being taught. i really don't know what i'm gonna do about this. and what's even worse is that whenever i can't solve a question (which is the case almost everytime i try to solve one on my own) it frustrates me so bad that i start to hate this freaking subject more and more. deep down, i know that i like math. but how can you like something that you don't understand?
