Need your prayers please

HI. Woke up Monday with shaking chills, fever, and severe diarrhea. At one point my temp was 103.6 and this was with Tylenol. I have been on clear liquids all week, and very little of those, except for a piece or two of toast. I have lost 10# but am getting very dehydrated. My pre-op testing is Tuesday and I am afraid my labs will be all skewed as a result of being so sick. I called the doc and he is out of the office but if no better, I will go to ER. I don't want this to end up getting my surgery cancelled which is on the 16th. I think it is an attack of Satan just trying to mess up this whole WLS thing. Thanks for your prayers, Jennie
