Sounds like you don't know much about engines, etc. I would suggest you take it to a mechanic.

Yup, you let things go long enough, they can certainly bite your butt.

To check for a blown head gasket look for oil in the coolant or the opposite. Do you see white vapor out the tailpipe especially when the engine is under load? Thsi is vaporised coolant. You may see decreased compression pressures on a compression test.

I would start with a coolant flush and refill and change the thermostat. They are cheap ($10). Make sure the radiator cooling fan comes on.

Sounds like your head gasket is gone. Mine made enough noise to make me think I'd thrown a rod and poured out white smoke. Head gasket is about $1000 to fix.
