screaming out.

does anyone else get the urge to just scream out long and loud at nothing and no one in particular? sometimes I am not even angry and I just feel like I should scream to untie the mysterious knot in me that I have no idea why is there. I know I brood sometimes but I never keep anything in me for too long, never bottling up my emotions. I'm straightforward and deal with my emotions and whatever thoughts come with them, sometimes brooding over them or taking a few days to understand them but after I take my time to do that, or just let my emotions go (like taking the time to cry when I need to), then I move on. So why should I have the urge to scream at the top of my lungs when I have nothing bottled up. Maybe it's just me being weird...who knows?
