Just not right . . .

I am having one of those days where things are just not right. I can't quite pin what it is. I feel melancholy, but can not seem to put concrete words behind that feeling. I can only say that I have this feeling that things are just not what they are supposed to be and I feel caught in the middle of it. Confused? So am I. It is hard to explain. It is just that I am looking at my life and the things around me and the situations I am interacting with and well, it just doesn't feel 'good' to be in the midst of it all right now. I don't know exactly why. Can anyone relate? Does anyone else have days like this? Days of undefined "yuckiness" - where you know things aren't right, but feel powerless to make them so? Maybe it's just me. ?
