I don't know how much this will help but I am also in school and working full time, I don't know how I am managing it at all; but I notice that if I stay up too late working on school work words will sometimes become scrambled on my laptop, almost like I'm dyslexic when I'm not. That's an usual indication that I have spend too much staring at a computer and that I'm just exhausted. I don't know what to do about the voices, but like everyone has said some schools do offer accommodations to help you get through. Most schools do what you to pass and succeed. This post probably isn't the most helpful and I do apologize, I wish you the best with that assignment. I always find that if I am really interested in it's not so bad to get through the assignment.
