Time flees and you have to try your best to catch it and hold on to it.  I hate how tired I get, and just watch an evening slip away.  Today was the busiest day of the study, and I had quite a migraine when I got home.  But now I'm so sad that I've seen so many of these days go by.  Writing this journal has shown me how often I let it go.  My kids are growing up right in front of me, and I can't even slow it down.  Wow, why am I so depressed?  Oh well.
