This happened on my 03 Ford Fiesta.
The clutch-pedal lever operated on the pin of the clutch hydraulic cylinder - the oil cylinder gave the pedal the resistance I used to feel with my foot.
Lever and cylinder pin were held in line with one another with a little spring clip - and the clip fell off allowing the pedal lever to drift to one side with nothing to press against - as a temporary measure I tied the two together with an electrical cable tie - it's been like this for the past four or five years.
You need to kneel down and get a torch into the foot-well to see what's going on.
I suspect that your problem may well be similar to the floppy clutch issue I had.
Good luck...
