Can I decide to be motivated?

I have to finish. Homework, exams, and of course I will, but right this second I can't seem to find the right attitude or the motivation. I am so angry. I must just be PMSing or depressed of something, it is those stupid end of the semester blues. I am nervous about break. I want home. Where is that? I want my daddy. Okay, now I will just go for a walk, or take a break or maybe I will convince myself I have that motivation, no it is not there. Oh well.
