97 honda gushed antifreeze and is revving up and down?

I got home from work last night and my honda was gushing antifreeze i could hear a hissing sound and i looked under the car and it was leaking from above the oil pan if that helps at all i looked a little bit and couldn't see anything i drove it about 5 miles today the temp guage was getting very hot and when i got home it was steaming very bad it still making a hissing noise i out water in it to try and find the leak but it wasn't leaking as bad and when i turned it back on it was revving up and then down from about 1k up to 2 or 2.5k i checked the oil and it didn't seem like there was any coolant in it thanks for any help you guys can offer!

Driving it today was a terrible mistake. One that might cost you thousands.

"Above the oil pan" suggests that it could be a leak from the water pump, or even the lower radiator hose. But you may have done far worse damage by driving it today. Have the car towed to a mechanic.

It doesn't leak as bad because it's out of coolant. It revs up and down because there's air in the coolant system, common for Hondas. Unfortunately, this will cost some bucks to fix but it needs fixed now.
