There have been many people who have posted this same question, and it has always surprised me a little how many did NOT tell people ahead of time (or after). Of course, I understand some of their reasons--it's nobody's business, they didn't want to hear negative comments, etc., etc.
But I was (& am) like some who posted above--I never hesitated a min. about telling people. I COULD NOT HAVE CARED LESS if there were some who were negative; I was just so thrilled to be having it. I had researched til I was blue in the face, and I read both the negative & positive. EVERYONE--friends, family, co-workers--was thrilled for me, or at least they had the good grace to "read" my attitude and keep their opinions to themselves if they disagreed! I only had 1 person (a dear cousin of mine who is an RN) who was very open about her negative view of RNY. People who are close to me by relationship or through work all know what a burden my weight has been and have seen me up & down in weight. I try to remember to frequently thank God for everyone who prayed me through the long approval process and surgery!
I don't bring my surgery up when in a group--don't want to bore people--but when they ask, I love to answer them; and the dumb questions don't bother me at all!
I'm a high school guidance counselor--had hoped to have the surgery back in June, but cir****tances prevented it til end of Aug. Bad timing, but there was no way I was putting it off til Christmas break. My principal & superintendend were very cooperative (obviously, I had sick days I had to use) and were just happy I was able to be at school for the 1st 2 wks., when the guidance office is packed w/ students! But anyway, in a school, there's NOTHING that remains a secret even if I'd wanted it to be!!
