Yeah - I have advice - because this is going to start happening again, I had such experience about a decade ago.
Replace both the clutch master and clutch slave cylinder. Bench bleed the clutch master before installing. You'll bleed the air out of the system as last step.
These cylinders do go bad at least once per decade, consider getting with lifetime warranty.
Clutch master cylinder tips
Remove fluid from the reservoir, use a 10mm flare wrench to loosen the line to the clutch master, then remove the two nuts from the firewall under the dash using a 12mm socket and ratchet wrench. Pull the clutch master out to the front. Bench-bleed the replacement clutch master, thread in the fluid line several whole turns by hand, then tighten the two nuts, tighten the fluid line with the flare wrench, add fluid, and bleed through the slave cylinder.
Bench-bleed the clutch master cylinder before installing.
Use a flare wrench for inital loosening and final tightening of fittings so they don't round off.
Loosen the line from the clutch slave a little BEFORE unbolting it from the transmission (and the reverse when installing).
Bleed out ALL the old dirty clutch fluid (brake fluid) wheen bleeding so no old fluid remains in the system (don't let the reservoir go dry, keep topping it off as necessary).
