it had a very difficult time shifting. Nissan said the mechanic thought it was a miracle I was able to drive it into the shop.

when a clutch blows all the way, you can move the pedal anywhere you want, and the shifter anywhere you want, but it the engine won't engage the transmission. it'd be as if you were giving the engine gas with the shifter in the neutral position.

one way to gauge how much the clutch has worn is at what point in the motion of the clutch pedal the engine/transmission engages. new vehicles should engage the engine/transmission near the bottom of the pedal motion, and a blown clutch engages immediately the moment you press it, if at all.
