I can relate to that! After losing 140 pounds, I still had what I thought were fat rolls. Turns out they were just hanging skin. It's really depressing to feel like even after all the work you've put in, you'll never be "normal," like you've blown any chance of that.
Boy oh boy, can I relate. I wish I had some advice, but I don't! It just sucks all the way around!
But congratulations on your NSV! Even though you may feel your body is still not "good enough," you're most definitely healthier now! I'm assuming your body functions pretty well and you can do almost any normal activity, so that's something! I would rather have two flabby legs that carry me around all day and let me run and play than two slender, cellulite-free legs that don't function. Form follows function! It is so easy to forget being thankful for all the stuff the body does behind the scenes and on the inside in favor of obsessing over perceived imperfections.
When I get down on the way my body looks, I find appreciating it for what it can do is soothing and makes the physical seem a little more trivial. And I'm sure you rocked that dress!
