a BCH in my DNY class

On Monday, we had debet in my discovery NY class, there were have 3 best debeter, two of them in my group, sounds like certainly my guoup will win, that's true. Afterwhile, a girl in the third guoup, which was the worse group, said: could the person who haven't spoke yet, and say some opinions? She was opinted at me. Therefore, everyone was stared at me, my group's leader asked a question from me, but I couldn't understand, not even talk about it, so I not only silented for while, but also my face was flashing, my heart were beat could not faster . Then, my leader turned around and said to me: "you get the say something" in a disdain way,........I really want to say F.....Q......U, but I didn't because I am eduacated,hmmmm.....
