Is this normal?

Is this normal? Is it normal that I can't sit where I want in my own home? Is it normal that I'm scared to talk when he's around? I'm haunted by his footsteps, the floorboards creek and all I want to do is hide. His masculine figure so big he could break me in half with one poke. 

His angry facial expressions when I talk or just be myself. I hold my breath when he walks past, praying I'm not doing something wrong or doing something that might make him angry. I can never seem to please, everyone makes it clear I'm their biggest mistake.

This isn't normal, this isn't 'family'. Being scared to watch TV or read a book, because somehow I'm doing it wrong or I'm in his way. I want to escape him, I want to be free.
