Abusive, angry controlling step-father

This morning was the morning for cleaning the house, so that meant I had to wake up early and leave the house because I am allergic to dust and dust mites.

My step-father told me I had to move my bags which were next to a tallboy in the lounge room downstairs because he didn't want them to be there. I told him to just leave them, that I would take care of them when I came back home. That was not an unreasonable request.

He wouldn't hear of that. He started screaming at me and told I had to do what he told me to do, that this was his house and he didn't want my bags there (they had some items of crockery which I hadn't packed away into the cupboards in the kitchen and a bag of CD's).

I was in the kitchen at this point, making a smoothie for breakfast (a quick breakfast so that I could leave quickly and not upset him because you never know when he's going to blow, he's so volatile). My step-father was screaming at me while we were both there and then threw a bag he was holding at me. Luckily it only had plastic bags in the bag (my mother recycles her plastic bags) and then they fell in the sink that was filled with water. I asked him, "what the hell is wrong with you to throw this at me?" and he responded by telling me that I had to move my things right now or else he was going to smash everything.

I followed him into the lounge room as he started to move my things to the door, so that he could take them downstairs, into the garage. I asked him what the point was for putting things in the garage, when I had to bring most of it back up again, because it belonged in the kitchen mainly. He told me he didn't care, that I had to just do what he told me to do because this was his house and if I didn't like it, I could "piss off" out of there and I should just "fuck off". He also called me a lazy bludger (of course he did because he cant think of anything else to say).

He then hit me. He hit my arm - he lashed out at me because he was angry and I threw the glass I was carrying onto the floor - it still had some of the smoothie in it - and the glass broke, shattering all over the floor and there was purple liquid everywhere on the floor too. Then my step-father went off his head again, screaming at me even more, calling me horrible things even more. This is such an untenable situation for me to be in and the violence, chaos and abuse I am constantly subjected to.

I was so upset by him screaming at me, for absolutely no reason whatsoever and that is why I threw the glass on the floor. It is unbelievably frustrating living with these people who yell and scream at me, flinging abusive words and actions at me because they cant control their emotions and take out their anger on me.
