Breakup Blues

I hate the breakup blues. Perhaps the most frustrating part is that I don't even entirely know what emotion is behind them at this point. Is it just plain old anger? Left over hurt? Loneliness?

Breakup blues always hit at the most inopportune time. Like tonight when I need to teach myself half a semester worth of biology.

Dang you, breakup blues. Dang you to heck.
