Which component of my manual transmission is my problem? on 2004 Chevrolet Cavalier

i barely made it home the other night after my 2004 chevy cavalier standard 2.2 liter's clutch petal lost all resistance. The car will still start and i can only shift gears when the car is off and even then it jolts forward already in gear. I'm not sure what the problem is exactly. Please help.

I would check your clutch Hydraulics first and foremost. Is there any Clutch fluid left in the reservoir. If it is low or empty, there is a leak in the Clutch Hydraulic System.
Sounds like u have a leak in your master or slave cylinder ..the master is the easiest and cheapest to change ,it's usually the first one a mechanic will replace ..replacing the slave cylinder involves removing transmission ..mine was of course the slave cylinder
