I've told my husband (who has been there every step of the way - even speaking for me when I was too emotional to do it), my parents, my best friend, some close colleagues and my boss (who is very understanding).
I wont be shouting from the rooftops, I too just cant stand the reaction. Yesterday, I went my GPs surgery to enquire about the referral, and the receptionist near enough shouted "oh you're the lady who's having the bariatric surgery". I was not best pleased, and told her she didn't have to broadcast it!
I do keep wondering what I will tell people as I begin to lose weight though, I suspect I will be honest.
I just have to keep reassuring myself that it cant possibly the easy way out, as I've tried everything else! But even so, I cant help shake the idea that I have failed at the "hard way" - its indoctrination! HaHa.
