I'm SO glad to have stumbled on this discussion my first day on this site. I have been struggling with who and what to tell. I, too, am very outgoing and tend to say what I'm thinking, but I also agree that there is a very real stigma with WLS. While there is a part of me that wishes and wants for this to be an "easy way out," I know from all the research I've done that it will be anything but. The problem is, most people in our lives don't have even a fraction of the knowledge and understanding we now have after having the decision, researched it, jumped through all the testing/assessment hoops, etc. Yes, it's a powerful tool, but you're so right that the tool won't work without the person behind it using it properly.
After reading everyone's thoughts and decisions on this, I think for now I'm sticking with my plan to tell only a few close friends and family members -- those I know I can count on for positive support. This is my journey to a healthier, happier me, and to the extent that I am able I won't let the world (and people) around me minimize the work, strength, courage, and determination that I am putting behind not just this decision but also the post-op road ahead.
Thanks everyone! REALLY glad to have found this site and forum!
