I have a 91 GMC Sonoma!! And I Desperately need help.. Please read!

What is your question?

I stopped at a stop sign and the clutch went to the floor, I figured it was fluid. So I filled it up and pumped it till got harder! I asked my wife of she was ready and I went to take off.. And the truck wouldn't move! It goes into every gear but when I let off the clutch.. Nothing! It won't move! Before I go spending all this money on shit I probably don't need..I really need just a little help on what it could be.. Or preferably what it is!! Please help me!
