Feeling used by my parents

Sunghwa • My name is Sunghwa. I'm wanting to learn more about managing my cycle.(:
During this year, I've been living at home with my parents. You would think that something like that wouldn't be so bad, for the most part, anyway. But,in reality it is pretty bad, and if my parents were actually nice, they wouldn't charge me anything just to live with them, right?
Well, that's not the case for me.): Get this, ladies: they've been charging me exactly $650.00 just to live with them, and to use basically one bedroom(that being mine,of course) out of the whole 4-bedroom house.
My dad always asks me to write out my check for the rent every 2 weeks because that's when I get paid at work, and because of the way that he asks for it, he makes it sound as if he has to have it right at that moment, and it drives me nuts.
He makes me think more of a tyrant than an actual person/parent the way he is whenever he's money hungry. My mom would rather support him in every single way than point out to him about how bad he's been treating their only daughter, so I just have to deal with this on my own, which really sucks.
I've been saving up money to buy my own place, and I've made a goal to be moved out by at least summer of this coming year. One thing that I'm scared to do is to stand up to my dad. He's really intimidating when he gets angry. 
They don't even treat me as if I'm their daughter anymore, either. They see me as a source for money, so that's pretty much it.At this point, I don't even have relationship with my father anymore, he's used me so damn much. It honestly makes me feel both sick and bitter towards both of them, but mostly towards my dad.
They do expect me to do chores every week, but I'm beginning to feel sick of doing those,too. I mean, what the point? Paying as much as I do to live there, I shouldn't have to do anything.
Then, they tell me that I spend too much money on the groceries that I buy each week. It's my money, so I get to decide how I spend it and what I spend it on.
That's all I wanted to say(for now anyway), so thanks for listening.(:
