I resent a fellow student because of how smart she is
You're upset with her because she's smart? Why exactly?
I resent that she's always top of the class and when I was in my career counseling session she said that I should go to uni even though my parents brought me up to be a mechanic.
I understand that you feel  resentful of your classmate and her advice. It sounds like she is trying to encourage you to follow your dreams instead of your parents' ideas.  Have you considered that your feelings towards her are based on feeling conflicted about your parents expectations and your own, and are not about her at all?
I just hate her.
She's just living her life and offering you advice, so it seems wrong to hate her for that.
