I feel nauseous, tired, light headed somewhat in a weird way, my stomach hurts, I have green poop, my lower abdomen aches and I have a slight headache. I try to sleep but I can't! I somehow feel as tho I've done this to myself by overthinking my situation, I have a slight toothache but that's unrelated I think. Any idea as to what I should do or is this just my mind playing tricks on me? I have a crazy fear of puking for some reason it panics me when I feel this way.
