Clutch stuck to the floor, heard 2 knocks and then I couldn't accelerate

So the other day I was driving and came to a yield, I pushed my clutch in to prevent stalling. It had gotten stuck to the floor, instantly reacting I took my foot and pryed it back into normal position. That's when I heard 2 loud knocks under the car, and now my car will start, I can move throughout all gears without pushing the clutch in, and when in gear, if I let go of the clutch it will not die. I had replaced a leaking slave cylinder a couple months back, and the clutch is still just as tight. So now my car is a big paperweight, I was told it could possibly be the throw out bearing? But if it was that, how could my clutch be so springy. Any info would be appreciated!
