1988 Datsun 210 fluid clutch cylinder and clutch Master cyl

I passed a car-shifting into another gear real fast-with the r.P.M.S kind of high-then when I went to go into another gear I had no cllutch-the pedal was hard.I had to turn the truck off, to put it in gear and get out of the road.I maded a big mistake by changing the slave cylinder and the clutch cylinder without reading instructions-now I can:t get a pedal to come back, I bleeded and pumped pedal until I was tired and when I thought I had a little pedal-bleeded the slave cylinder and pump some more for hour:s and still nothing-what i:am I doing wrong--are is it the clutch gone.
