Sounds like a head gasket has failed need to have a shop check this before further damage to the engine occurs www.repairpal.com/directory and your can see a online estimate of repairs here www.repairpal.com/estimator

The same problem with my honda civic 94. The head gasket was blown. check your oil and if it's look like a hot chocolate that means your coolant and oil have mixes. The temp. gauge go's up due to empty coolant in your radiator
