This evening I was cruising on a toll road and came to a toll booth. After paying I was accelerating into traffic and for the first time ever I ground the gears shifting from 1st to 2nd when a truck merged into my lane. Immediately after my inept self ground the gears the clutch pedal went limp and basically had no resistance until it was almost to the floor. Shifting into any gear was difficult and I had to rev match the throttle. I was able to limp it the Nissan dealership near me to drop it off. When I was showing the service tech what the issue was almost seemed back to normal, although I wasn't driving it, just sitting in the parking lot pushing the clutch pedal.

Any idea what it is? This has been one of the most embarrassing days of my life. Doesn't help that I had a cute lady in the passenger seat. :/
