You probably started out with a leak, a bad cooling fan or a stuck thermostat. Without a leak, if the engine overheats, coolant will boil off out of the coolant reservoir and 'disappear' from the system. Many leak sealers actually cause more problems than they solve, and can clog the radiator,heater core, thermostat, and some of the smaller passages in the engine. If you have driven it while overheating now, it's probably beyond simple fixes, and will likely need cylinder head gaskets at the least. Those cars are also bad about CRACKING cylinder heads, which would need to be replaced. Two other side effects many people overlook: the excessive heat will also chemically change the engine oil, causing excessive wear in the bottom end of the engine, as well as transferring the extra heat to the transmission fluid, and causing damage there. I'd advise taking it to a trusted qualified mechanic and taking it from there.
