help!

hi everybody.... well i have a 2003 1.8T GTI and my clutch is not working very well......  first of all to start i have to release the cltuch at a high point and when the car starts running, it starts really slow and it sounds like if I were driving it with the clutch pressed. and when i make a gear it sounds like if i was pressing the clutch and the gas at the same time and the rpm goes to 5 and comes back to 3..... it's been like that since sunday and i dont wanna drive till i fix it so finally im taking it to get fixed tomorrow but first i would like to know where the clutch is in this GTI.....
