Brain Drain

I have reached a level of mental stress that I have never experienced before in my life (not to be confused with emotional, and also physical, stress, which are quite different). Mental stress is exhausting - it breaks you down in ways that you don't expect. And I'm in it - right smack in the middle of it. My brain is in shock. And yet it's impossible to slow it down right now. And it's not just about all the work I have to do in the next few months - although that is a huge factor. But coupled onto that is all the other stuff - planning, organizing, doing preliminary background research on the feasibility of my upcoming research (don't even ask), and just thinking, reading, thinking, reading, thinking, thinking, THINKING. Usually my brain can prioritize and manage things in a very rigidly organized way; anyone who has ever worked with me knows that while my desk would always be messy as hell, piled high with papers, when it came to getting the job done I would do it with a very narrow margin of error (and I'd usually catch those errors before going from PPRD to PROD, to print, or publication!) because my brain was right on top if it. But now my brain is just staring back at me saying "ARE YOU KIDDING ME?!?" Oh, I know I'll get it done, hopefully with the same minimal margin of error - the question is will I manage to get it done without throwing a bottle out my window at 2am at the drunken louts on my street?
