I kept getting the same thing from folks at work.  I finally honed my answer down to the following:  "I have three choices... #1 Stay the same weight and eventually end up diabetic, hypertensive and with knee replacements.  #2 Start yo-yo dieting *again* and end up even fatter than I am now. (and then add in the probs in #1)  #3 Have WLS now while I'm relatively young and healthy and live out the remainder of my life happy, healthy and fit."  They would all sort of stand there, and then say  " Yeah, I see your point."  And that was as far as it went

Only one person sorta kept at it, and I just told them that apparently my surgeon and my insurance company felt I DID need the surgery, and I thought they probably knew what they were talking about.    

Congrats again, hope things continue to go well for you!
