I'm 25 and get banded on sept 14. I was so scared to tell anyone I was even thinking about the band. Unlike u I am surrounded by overweight people, except for one of my sis who has never worked out and is so tiny even after two children. When I told my fam they just said,"you know what u need to do to loose weight. Diet and exercise. Just do it." even my best friend who is overweight said this to me.
After they have witnessed me being depressed about my weight for the past year and genuinely trying and failing to loose weight, they are supportive. I have asked them not to really tell anyone else. Just don't need the extra judging eyes coming my way while I am going to be working hard at loosing.
