I agree with everything they have said so far. I had the band back in 2008 and have recently had it removed and the sleeve done. Best decision of my life. The first time around my oldest daughter gave me great support until i started to get thinner then her, it then ended and she made my weight loss all about how horrible i was making her feel. This time around i expl to her that if she cannot be my support, then just don't talk about it at all.
It is very important to have support... lesson learned. If they cannot be there for you now, find someone who will and just know later down the road, when your healthier, and are living your life and enjoying it, they will come around. People get frightrened, sometimes they only hear the few negative things out there and make it all they hear. Just do whats right for you. No one can make those choices but you and watch out for those who would sabatoge you!
Also don't feel disappointed, this isn't about them, but you. Get used to thinking that, and be happy in your decision.
btw, im 30 lbs down and 22 days out!
