i am disturbed

a powerful and inexplicable sorrow steals over me. my insides say, "you are intensely sad," but will not say why. could i simply need some fiber-filled fruits and vegetables in my diet? should i only think more of taking a daily vitamin? or, perhaps, something deeply disturbing and horrible is lurking in my subconscious mind (if such a thing exists), telling me that all is not well . . .
i find this experience to be unfamiliar and do not know how to handle it. maybe i can only describe it and move on: i am disturbed.
