Moving out;;

So I'm moving out. I'm nervous. I am only seventeen. Granted that I lived paid rent and was basically on my own, I still lived at home. Now my dad is trying to  be an a s s  about it. Telling me that I have to pay him rent for a month when I was only there  for a week, and I'm not going to be there fro the rest of the month so whats the fkn point? And then there's this whole he has my money in his bank and I really am beginning to think that he spent it because everytime I ask for instance; I was supposed to move out today. he won't let me leave until I pay him rent so I told him to take it out of the eight hundred that I have in the bank and I'll put it back tomorrow when I get paid. His response was, We'll see. Who the f*** says that? Seriously, if he did in fact spend my money I will go crazy. grr. why can't he just be normal?
