@@brandyshell - this is my very first post in this forum. I just had RNY surgery last Weds (Nov 30), and I understand your worries exactly.
I too was (and still am) "excited, nervous, and scared all at the same time".
Until a week prior to surgery, I only told my parents, my siblings and my wife's siblings. Last week, my wife convinced me to share it with a few of our close friends. Fortunately for me - all family and friends were supportive, even if they might think it's an easy way out. Although we know it isn't!
Bottom line - you know it's right for you, and that's what you must keep telling yourself - despite the naysayers. It's likely the best way to have significantly increase quality of life going forward as well as massively lowering your health risks.
Sure there are risks with surgery -- I was increasingly worried about complications the closer my surgery came.
Thank God, my surgery went very well - as yours is likely to go as well.
If some of your family members are negative - you can simply choose not to discuss it with them. Or one possible tactic is to say that the surgery is not the solution - it just buys you 12-18 months to change your relationship with food. Remember - you get to choose whether to talk about it or not with those around you.
My best wishes to you, brandyshell -- believe in your decision and be determined to succeed!
