Sad story - Father made us all unhappy

I'm 19 years old, living in a complete and "happy", at first glance, family. Father, mother, me, my sister is 14 years old and brother is 11 years old. For all people, we have exemplary relationships, kind daddy, a modest and sweet mother, and we are children "happy" and loved by our parents. But it's only in public. We have a big house, two cars. But in fact, it's not like that at all. Father has been building this house for 20 years, one. And he refuses to offer assistance to acquaintances. But we are forced to work every summer, we wear bricks, we heap rubble and all this for his spiteful shouting and kicking. We have never been at sea or in the camp, in general nowhere. We are forbidden to watch TV, only children's films.

I can not get a guy and you can not go anywhere, either. There is not enough food in the house, only what the mother will buy. He does not give money to the family, she does not allow her work, and she almost begrudges money from him with an outstretched hand for food, which he later eats. In school and technical school we have nothing to get together. And he opened the roof to cover, and when it was, all the plaster fell down. Now a pile of clay lies in the middle of the house, and he does not allow it to be removed.

My mother now went to the sick grandmother, she can not be left alone, and now there is a famine in the house. Recently, my brother took money from him to buy food, because there are only small potatoes and cucumbers in the house. But he recognized and punished him and me for the fact that I tried to protest, now we have to saw thick logs for firewood in the heat with a dull saw. Although he has a chainsaw. I saw the whole day with my brother, my father did not even allow me to rest, but I could not cut it off, and he called me "an empty place."

And in the winter the mother chop wood into the cold herself, and he sits and watches TV or plays on the computer. Mom, he says that he spends all his money on construction, and in fact buys collections of stones, machines, books. She knows that he is lying, but he tolerates and is silent, but he recovers from us. Constantly arranges scandals and fights. And he is with her at the same time, but only when they shout at us, and so he does not pay attention to her.

I'm already tired of this life, I understand that I can not leave now, there is no money, and I have to finish my education, and my brother and sister are sorry. I hate my father, but I do not know what to do, where to turn? After all, for all those around us, a good and prosperous family, if they do not believe it. How to cope with all this?
