Is it normal to hate my family because of these reasons?

My mother are in process of divorcing with my father. She says that it is my fathers fault.

My mom is mostly doing nothing, but slacking in her bed and complaining about her life, while doing nothing about it. She has no work. She is constantly getting drunk and one time she got so wasted, that she even decided to go sleep OUTSIDE. And it was really cold outside. After i convinced her to go inside she called me something like: Stupid morron. I felt really bad about myself.

She always talks to me about her problems, and if I don't want to listen to her she gets mad about it and says that noone cares about her. I have a lot of problems too, but she never asks me about them or is interested to talk to me about my problems.

Once my dad had some of his friends invited over (really cool dudes). But my mom was sitting at the table, getting drunk, and calling my father in some really cruel names. After he had enough she punched her in face. Of course i had to protect her so i pushed my father so strong that he fell on the ground. He was so mad at me that he almost punched my in the face.

My dad is a fireworker. As a fireworker, he gets enough money (500 euros) for our family: Me, my younger sister, my older brother, my mother.
But money somehow is never enough! We grow vegetables and fruits in our garden. And thats what we mostly live of. My father spends around 100 for fees and 100 for other foods. Noone has any idea where the rest of the money goes, and thats why my mom thinks he is cheating on her.

My dad doesn't really care about anyone but himself. Today he even made me help repair some cars, even if I'm sick and got temperature around 38.5 (celcium).

My sister is 12. She's really ignorant and arrogant. And she is really rude to me and others as well. She is dominant as well and always wants others to do her house work.

My brother is 22. He is still studying to be computer programmer. I have never seen him programming anything. All he does is plays video games for 14 hours a day. He has to be at school 2-3 days a week, but yet he has never been interested to get a work. At school days he stays at school dorm. But all the other days hes home, playing video games. We live in a same room and it is hard for me to get asleep because of all those clicking sounds. But he doesn't care about me.

About me. I am 19 years old and this year i will get my diploma and attend to highschool. My hobbies ar fishing, woodworking, motorcycles (I have 50cc Sachs Madass). I love going to movies and theater, concerts and other cool stuff.

At the christmass time we have to describe each other character in my school. And this is how my class mates described me: Friendly, cheerful, quiet, intrusive, smiling, very fun to be with, serious, funny, shy, clever, humoristic, elegant, handsome, beautifull, smart, gentle, very sweet against girls, loves to play games (yes, sometimes i play candycrush :D )

is it normal that i hate my family? Somethimes i wonder if I am adopted. At the moment I am desperetly looking for ways to earn money so i could afford my own small appartment in the city. And i can't wait when i get away from this house.

So what do you think of me and my situation?
