scared silly

Sitting here in Chemistry, sweating profusely, and I just can't get it off of my mind. If I feel like I should do something, why can't I just do it? I always make myself so anxious, and I cannot seem to find a way around my cowardice to face what I know is right. I have never been the least bit confident in this certain area, but I feel as if I can overcome this test. I can do this.
