Do you have to love your parents?

You see, my mom is being unbearable, and she is ignoring me because my marks aren't good enough for her. I'm getting around B's and B+'s, sometimes A's, but because of my report card, she won't talk to me. My father said he approves of my marks, but not my mother. I'm starting to think I'm useless to her, and if she's ignoring me, I'm thinking of the "If I'm useless to you, then don't bother speaking to me" I try my best to have my love for her and stuff, but I'm almost at that line. In the bible, it says Honour your Mother and Father, as that means to respect them, I don't remember anything about loving them. I do respect my mom and dad, it's just how my mom treats me and stuff. Any help?
