Sometimes there are things that you have a visceral reaction to. My friend Brian, who was a psychologist, told me once that this is a form of PTSD.
Most mornings I wake up and I'm ready to kick ass and take names. I'm happy, I'm positive, I'm excited. But as we roll into October there always seems to be this very low-lying "hum" of anger/sadness/rage/fear/frustration/confusion/disbelief that I try to tune out...a hum that continues to vibrate even when I talk loud enough, stay busy enough to mask it. And once in awhile something or someone cranks up the volume to levels I can't drown out, and I just have to clap my hands over my ears and hide my head under a pillow.
