Losing It

Every time I try to concentrate on doing something, I just get jaded.

I will look right at the thin air, something preoccupied my mind. By the time I snap out of it, time passes by like a bolt of lightning.

Why is this happening to me, when I really need my concentration the most?

I know final is just a few days away, and I am not familiar with even one of the subjects that I am going to sit for in a few days. To pass it seems so impossible right now. But I am not going to give up without even trying. Or am I already giving up?
