if you can get it into gear while the car is off, the problem lies within your disengage mechanism (disregard spelling) the first thing to check is your master/slave cylinder... push the clutch in and have a friend check the movement... if movement is low, check your fluids/bleed... if you bleed it and movemtn is still low... look into replacing your slave cylinder, also look into the seal inside the car for the master cylinder
if all that is fixed and fine... look into getting a new clutch kit, it'll come with presure plate, clutch disk, bearings... and most OEM replacement clutch kits are affordable
start at the basics and move up
i will check that as soon as i get the car towed to my house.
