Depression

Sometimes I wonder if I'm slightly bipolar. The ups and downs of my moods are strange to me. I can't always make sense of them. Yet many, many, many of them follow periods of stress either academic or social. I'm trying to do homework right now, on a tight deadline, but I just can't concentrate and instead of getting anxious like I use to, I'm beginning a draft of this, reading a chapter of something else, staring out the window...

It doesn't help that the latest section of my abnormal psychology class was on mood disorders.
