Help!! clutch petal stayed to the floor

[coyotedance]

Hi

when I drove off this morning i shifted from 1st to 2nd and the clutch petal stayed to the floor,,I made it home like that and started to investigate the problem ..the 1st thing I did was pull the petal back up now it won't go back down..You can push on it with 2 feet and it won't budge..so before i get into this problem where should i start 1st?...I would appreciate any help I can get
This is a 1982 240d By the way..

thanks for your time
