Ah, reminds me of a moment of mine, where I was in university and we had to read something in english out load. The block was so hard, I couldn't even start reading. Made some noises, tried to say the words but I just couldn't. Wanted to flip the table so bad. I just stand up, picked my things and left. I don't remember even how i left university, I was this frustrated. I just went home, punched the walls and cried and fell asleep trying to forget it and ease the pain. I know what you felt and im sorry to hear that other person had to go through this
