This era of Honda Civics are commonly reported to blow their head gaskets.
If your radiator is getting empty, it's likely all going into the cylinders. Check your oil immediately, and see if it's milky/muddy. If so, get the car booked in for repairs, driving it with a blown head gasket can lead to catastrophic failure of the engine.
