2002 Subaru Impreza

Hey, I've lost all my gears 2 days ago, im trying to figure out what the problem might be, when I put my foot on the clutch it gets stuck to the floor, I've checked the cable it seems alright, theres no leakage from slave or master cylinders, my folk looks twisted, when the clutch is down the folk doesn't look like its releasing the bearing.
Im guessing I have either a faulty folk or need a new release bearing but Im only guessing.
I would appreciate any ideas on what my problem might be or what the problem is.
If you know what the problem is, could you tell me what parts Iwould need to fix it. Thanx
