Happy days die...but some survive

I don't like my formteacher. He thinks he knows me. But he don't know anything. If I say something he analyse it and think that he know what I'm thinking. I don't like this person. But I smile when he looks in my direction and think: "Oh my good. You know nothing". Well, he said that every student have to do a performance in the beginnig of a lesson and summerise the lesson before. And now it's my time to do this. I don't know anything about physics. It has never been my strong point. And so I asked my father to help me. Well, I love my father, that's for sure, but he isn't a good teacher. I don't always understand what he wants to tell me. And so he shout at me. I'm afraid of him. The things he say are hurting me. If he is so angry he say that I'm stupid, that I don't belong to the school I go to every week. I'm not intelligent enough for lessons like physics, math... . Well, he's right. I'm gifted in languages or lessons which I have to talk a lot. But he said to me, that I don't want to learn. That I don't want to improve me. And that's what is not right. I want to improve my school performace and I learn a lot for it in my free time. But nobody seems to see it. They tell me that I'm lazy and I don't want to improve me. And so I wonder, why should I struggle if nobody is seeing it? Everybody is thinking that I'm stupid. And I know that this opinion will never change. I can do everything, but the people will still believe that I'm stupid. So why should I try to change it? Nobody sees my struggle, so what should I do? Now, I will try to finish my physic performance...
