Sounds like you are describing a worn clutch disc. Trying to force the car to move will only cause the disc to slip more and overheat. That can cause hot spots on the flywheel surface that can't be machined out. The flywheel has to be replaced for that to prevent chatter when engaging the clutch.
It is also possible something came apart with the clutch release mechanism. That could cause a low pedal, but if it is causing that slipping, it is still going to destroy the clutch disc.
