A Very Bipolar English Lesson

This is one of those quirky random finds that fall into my lap occasionally when I'm searching for something else.
It's an English lesson which contains poetry, philosophy, and a bit of psychology.
It's a nice illustration of what it's like to walk this world with a bipolar brain.
I personally don't flip a switch on my moods at the drop of the hat most of the time. I can generally tell when I'm cycling from up to euthymic to down. However, things can happen which can push me into a horribly depressive mood when I was in a fairly good one.
I just thought it would be fun to share this with all my other mental misfits!
