Extreme feeling

One more hour and I am heading on my way to take my driving (hands-on the wheel) test. I can’t just resist having this extreme feeling right now. I can’t even explain this, some kind of a feelings that, feels like I have a fever for a sudden. I really don’t know maybe I am sick now but I’ve been doing okay earlier. I was trying to relax but I can’t stop my brain from driving me crazy. Oh well, maybe I am just tense and hope this will be gone before my actual test. Oh gosh, help me!
