You knew that I’m deranged

As if I suffered from a severe bipolar disorder. I can't seem to find a way to balance it. Some kind of Dr. Jekyll and Mr. Hyde, vying to control me, fully aware of each other's existence. That's how I go from being a vegetarian hippie to a fierce beast, with an uncontrollable urge to rip flesh. Figuratively speaking, of course, but you get the picture. That's why, sometimes, instead of subtly suggesting how boring I find what someone's saying, I keep it inside.. until it bursts out, and I coldly point out how much better the world would be without them. It seems to be the endless pattern of my life.
