how can i fix my clutch on my mercedes vito van 2001?

i have never had a problem with my clutch until now it was fine i stopped parked up for 15 mins went to drive away when i was pushing the clutch down it was like ther was nothing ther until about 2 inches from the floor thats when i was changing gear then the clutch stuck to the floor so to get home i tried to pull it off the floor but when i did i snapped the clip on the hydrolic ram but the clutch shouldnt still be either sticking to the floor and not pushing its self back up can any one help?
