Why do I do this to myself?

I am being so Negative Nancy today.  I think it might be a combo of many things, including the fact that I have gone to bed at 5 am the last two days, frustration with coworkers (see last post), people being disrespectful, especially when its directed toward me, my sunburn, the family reunion I am missing, and the fact that I have no friends here and all my friends are having a great time together in Provo, among other things.  

I hate feeling like this.  Something needs to change.  And it has to be me.  What I am going to change...I don't know.  But whatever it is, I need to figure it out, and fast.
