Book Reports / Narrowing thesis enough, Help writing essay on Hamlet. [5]

I need to write an essay on Hamlet for my British Lit course. My problem is that I can't narrow my thesis enough for the paper's length. It should be between 5 and 10 pages. It's a formal paper but not a research paper. I want to write about how Hamlet is surrounded with untrustworthy people and how his affects his behavior. I can't figure out how to narrow it down or organize it. Please any suggestions would be great. I tried other sites for help but they only want to write my paper for me.
