Yep, everyone here is correct. Without a doubt you've got a blown head gasket on your hands. Coolant has to go somewhere, and external leaks aren't subtle. You'll see them if they're there.
So it's got to be going into the motor. If you've got coolant in the oil that's a recipe for serious engine damage. Of course in small aluminum motors overheating will lunch them right quick so you have to be really, really careful about that. If you warp the head it can be nearly impossible to salvage the motor. If you warp the block it's done for. Stick a fork in it, get a new motor or a new car.
Sounds like you probably have a leak into the cylinder. I had a shop put a new head gasket in an early 90's Civic last year to the tune of about $1200. I had them do the timing belt, an oil change, and a few other touch ups as well. As long as you haven't warped the block or the head (too much) it can be fixed.
But don't drive it. Not an inch.
