Heh. I was in the same boat as you. I got my wisdom teeth out before college too. I wasn't as nervous as you are, but then again it was early in the morning so I wasn't quite awake. I remember going in, signing papers (I was 18 at the time), and sitting in the chair. They put an IV in my arm, I asked them was it was, and it was the pain killer along with some saline solution. Before they put the mask on, I told the doctor, the nurses, and my mom that I was going to count backwards from 100 and see how far I can get. So the mask came on and I started to count. 100... 99... 98... I got all they way down to like 90 then I barely remember starting to say like "78." It seems to be that things wear off over time, and I started to come out of my slumber, the doctor freaked out and put like a 10x bigger dose in to make my sleep.
After the surgery, they helped me to a resting room where I tried to sleep, but I couldn't really, my cheeks were HUGE! So they helped me to my car. Of course my mom, being as nice as she is, decide that we should go get some bagels for everyone. Me on the other hand was upset and tired and I really wanted to go to bed and sleep. Once we got home, my brother helped me out of the car, and had to practically carry me upstairs. Before I passed out on the bed, I mumbled, "I got to 78..." He laughed.
Anyways, it isn't all that bad. Just make sure to eat REALLY REALLY REALLY soft foods afterwards. I ate mostly apple sauce, mashed potatos (sp), and Jello.
