Sounds like the clutch pedal has turned into a brake pedal, after reading your first post.
Resistance when depressing pedal, something would be binding, T/O bearing on bearing retainer alittle tight?
From your other posts, this is about all it could be, you mention clutch will move all the way - does this mean it works as normal, just very hard to push? Does it engage/disengage as it did before the "binding"?
Could be a bent fork, broken pressure plate, or worn bearing retainer where the T/O bearing rides on causing misalignment. Or, slave cylinder binding up due to heat, as in piston/cylinder clearance.
