I don't think your teacher hates you, and I don't think you are a bad student. It sounds like the music feels too challenging for you at this time, which sucks the fun out of playing. This is a mistake teachers sometimes make, they give you something that is too challenging, often with the best of intentions, but it's simply not working for you. You're not supposed to play pieces that are too hard for you at this time, that's why they are labeled "too hard". Have you discussed your feelings about this piece with your teacher?
