Okay this may sound stupid but in your rush and then subsequent panic, did you press the clutch pedal down far enough when starting the car? I've done it before. In the first couple of months of ownership. Went to get in car to go somewhere, it didn't start then started to panic and eventually realised I wasn't pressing pedal down far enough as I started panicking. Never had an issue since, so I suspect it was just be being an idiot.
