Citroen Dispatch?

Hi, can anyone help please?
My clutch pedal suddenly went and felt like the pedal ratchet had gone.... if it had one! After pumping the pedal I can get some gears but with extreme difficulty. I replaced the cable with no change, then renewed the clutch, and cant get 1st or 2nd without lots of effort and crunching. The linkage cables look in good condition and not broken and the gears are still there which makes me think its not the gearbox. Seems strange to be all ok one minute then totally useless. Any advice would be much appreciated.
