Why do I keep trying to prove to my parents I'm not an idiot?!?!

Tonight was the "Test The Nation" IQ test on tv. Jeff, my mother and I took it. Well my mother and I actually tied with 51 out of 60 right for first place. Jeffgot 42 out of 60 right. So what does my mother do?? I was hoping she would finally realize I do have a few working brain cells and I am actually kinda smart..but no. All she does is tell Jeff how smart he is and well he did. Then she asks him how he did on a previous IQ test he did. Then she says "So see..he got a score just like ours on another test."

Does she say ONE word about how well I did?!?! NO!! Oh I take that back she did say one thing. I TEASINGLY asked Jeff how it felt to lose to TWO women to which my mother bitched at me saying I didn't know when to let something go.

She is constantly telling Jeff how smart he is..never telling me how smart I am. Then when I FINALLY prove that I am smart and she doesn't say a fucking word except to bitch at me!!

Is that fair?!?!? I don't think it is. I feel like crying because of this. Am I overreacting?? I'm beginning to wonder if each day my place in the ranks with my mother is slipping further and further.
