Emo without a cause

I'm sort of depressed. Which is weird - there's no reason for it. Nevertheless, the depression trolls that lurk under the metaphoric bridge of my concious mind (be nice, it's 6am) are alert, and jumping on any thought ambling across, that seems like it might lead somewhere miserable.
It's not a matter of just trying to focus somewhere else - really, I'm working very hard to distract myself.
"Well... lets see what's on TV. Hmm ET! Trashy. Has potential.
Brittney Spears! Geez, she looks depressed. And bald. With two mini K-Feds. Sucks to be her."
And then I'm thoughtfully reminded that Brittney is stupidly, stupidly rich and could jet off anywhere at a moment's notice. Its not as if I cared ten seconds ago, but right now this situation seems terribly unfair.

I have a lot of things going right at present. Why the hell do I keep trying to sabotage myself?
