actually honey now that i read the whole board ur describing is how i have felt all day today. i have had diarrhea, pressure in my head, headaches, spacey, feeling like i'm onna pass out, kinda light on my feet, nausea, ect. i honestly thought i was sick and then it went away after i finally relaxed. the cold flashes your describing though i get all the time when i'm anxious thats nothign to worry about. remember that anxiety can createall kinda of physical symptoms. u name it, it'll create it. your fine love, i highly doubt its anythign other than anxiety.
