PLEASE HELP choosing a topic

Hello all! I am a college sophomore. In less than twelve hours I need to submit a 12 page essay about Hamlet. I am supposed to include another work from the course to argue with it. I was thinking Don Quixote. But if I can write a good paper without a second argument i would rather do that than submit a bad one that includes two texts. My problem is that like Hamlet I am indecisive.
This is the assignment
--The final 10-12 pages, double-spaced, size 12 Times New Roman, including works cited. These will be an argumentative analysis on a topic of your choice. These will consider two of the texts we cover.

I want to write a great paper but I can't decide where to focus it. I was thinking about the idea of madness, how hamlet is relative because it focuses on the individual, Hamlet and queer theory, how it is philosophical, or existential, so on.....The problem is I do see hamlet in myself, and this makes it difficult. I am intrigued by the philosophy in Hamlet, what it means to be alive, and so forth. But I am afraid that if I take this route I will not properly analyze the text and I will not have a central argument.

The point is I cannot decide or make a thesis statement to save my life right now. I am afraid I will make it a philosophy or psychology maybe even sociology paper.

Any help to get me started on a solid and workable topic would be so deeply appreciated. I am open to ANY ideas.
