betty - come on sweet, now's the time to just focus on u and ur body alone, you've been hanging out for this op for so long now, don't do ur body any injustices at this point by focusing on other stuff that is only going to make u spiral. Let ur sister and other family members focus on that now. you wanted this op and it is now around the corner so shut out the other noise and listen to ur own positive thoughts talking to ur own body and willing it to produce a positive outcome. This is ur pre-op chance to be selfish and nurture you and you alone.
