I figured out how to make all those thoughts that were troubling me finally go away:

     Just work.
        And study.
   (Maybe sleep.)

My days are too filled with trivial diversions to allow for abstract comtemplation now. It wasn't a choice--I didn't think it would be anything like this, that I would feel so tired, and that I would have such trouble sleeping. My second wind comes around 12 and I usually can't get to sleep for at least two hours afterwards.

I sometimes want to crawl away from all this work. But I know as soon as my body begins to wind down my thoughts will start back up again. And none of us want that...

Force your body to move until you just can't...fall into bed or onto the couch. When you can't find balance in your life the only thing you can do is alternate between the extremes.
