I feel sick then I feel well. I am cold then I am hot. It is not an infection, I am not sure what I have got. I think perhaps that I get it when you enter the room. My pulse quickens and I feel light headed. Am I having a heart attack, I cannot be sure. I know when you speak my name that I want to fall to the floor. Love seems to be something that has taken hold of me. How can one emotion have so many different symptoms, can anyone please explain it to me.
