Sleepless Nights

It's almost 2:30AM, and I can't sleep.  I spend so much time sleeping during the day that I am up pretty much all night and into the early morning. Over the last week, I went to bed at around 5AM almost every morning. The reason is because when I lay in bed, my mind races. I think about a lot of things that have happened to me and that I have done, mostly things of which I am not proud.  I know that I can't change the past, but it is definitely hard to move on from what's done.
