How am I going to have enough money to pay my rent?
That's quite a predicament. Are you getting any financial support?
My father is putting in some money, but it is about $10 short of what I need to pay the rent.
You need to budget your money appropriately to be sure that you can meet your financial obligations. You should not be dependent on your father to help you pay your rent.
He is my father and he is helping me out.
It's important to learn how to budget so you won't be in this predicament. It's nice to have a father that can help you out in times of need, but wouldn't you prefer to look like a responsible adult and take care of your own finances? I can always teach you about money if you want.
