i need help
 

i have an rx8. and recently while driving, my car has been reving at high rpm just to move. around 7 to 9 rpm. but the thing is that as high as i'm rpm-ing the car barly moves. the when i'm driving it doesnt go past 45 mph. the cluctch feels like its not catching. i can throw it into first gear with out pressing the clutch. i can also throw it into any other gear without the car stalling. the clutch when [pressed sometimes doesnt come all the way back up.

Clutch is toast.
