I understand how you feel. We are heading there on Friday, newbies as well. I'm 51 and have struggled with my weight my whole life. I had two 10 lb babies and a c-section. I"m redheaded and pale. I've lost weight but am still nowhere near thin. My BF thinks I'm sexy and I believe him-because we are there to rediscover each other, and if there are new friends in the mix at some point, that's good too.
I don't have a perfect flat stomach and I've never had any sort of cosmetic procedure of any kind. If someone has an issue with how I look, they are free to look elsewhere.
