HELP what did i break?

[onebadbowtie]

i got stuck in a snow drift and went to back up. put it in reverse and let off the clutch and it jumped out of gear. the motor still runs good but the truck wont move. the clutch pedal goes to the floor and wont come up unless you pull it. and you can put it in any gear with the motor running and not pressing on the clutch. what did i break? and its not the drive shafts.

thanks in advance James
