If it is not turning (like it should when the pedal is depressed) it may be locked up. The squealing you hear would be the throwout bearing sliding/ grinding against the pressure plate release (probably a diaphragm type system).
This puppy should spin freely against the diaphragm, anything else would be damaging to the system.
That screaming/ squealing is a call for help before things really get messed up leaving you stranded/ in an unsafe traffic situation/ pawning all of your stuff.
Right now your pocket book might could tolerate "just" a new throwout bearing.
Further damage may result in your pocketbook screaming/ squealing!
Do not do like my sister, ignore it all until the wheels fall off!
Be safe/ take care of your vehicle, it will take care of you!
