I should be happier than this

I'm going to assume that I'm just tired and have listened to a little too much Evanescence this evening to be in control of my emotions because for some reason I have this need to cry. I have no idea why except that I feel overwhelmed right now. I have too many tasks on my plate...things that I don't exactly know how to do. But because me have an obligation to stakeholders (there's a nice baldridge word for you), I have to plow through this.

It's funny, I'm on the threshold of getting what I've wanted for over a year and yet, I'm not as happy about it as I thought I'd be. I know I'm not a glutton for punishment, so what's my problem?
