Skeletal birdsong

Anxiety, me? I don't think of myself as an anxious person. Keep busy during the day and keep pushing the anxiety away 'til it wakes me up in a sweat, yeah okay, that makes sense, but if I let the anxiety out -- screaming, scratching at the cage which is my own body -- if I let the anxiety out -- dark stabs of fear, like being grabbed from behind -- if I let the anxiety out -- lift weights, walk hard, harder harder harder back bent head low -- damned dull light today, clouds pulpy black and grey, trees skeletal -- birdsong, no, not the defiance I take it for, but simply birdsong, existing long before and long after me, birdsong for no other reason than birds sing -- comforting -- walk hard but head up -- grace?
