Dropped Camera!!!

My camera fell the other night. It's usually inside my padded camera bag which cushions the fall. This time, however, it fell right out of the bag. Sigh. Thank goodness, it's still working but I noticed that the auto focus takes longer. And I think that the light sensor might have been affected too. Sigh. I really do not have the budget to get it checked out and repaired right now so I'll have to make do. Does anyone know if it gets worse if I don't get it checked out right away?
