Financial Aid – To Appeal or Not To Appeal?

so i received my finaid package from BU just now. it’s better than previous years, but in this economy, it’s still not enough. essentially i’m being asked to give up my entire summer’s earnings. that just can’t happen since it’s summer – life costs money. i’m either going to have to apply for an unsubsidized loan or appeal the decision. anyone have any experience appealing? if i were to get just $1000 extra grant money, that would be enough.
