Beautiful at any size
You know, I've been having similar thoughts lately. I am not thin, but I am thin for ME (160ish). I used to have a large chest and a BIG butt. I mean, I was teased about that butt, people loved that butt, people smacked that butt...and it was large and in charge pretty much since I hit puberty. Now, my butt has deflated and I find myself missing it a bit. I tried on a dress today for a wedding I am going to, and my bum just seems so flat.
BUT, pun intended, I am grateful for my progress and it is such a very small sacrifice for my health :-)
I know I am going to miss my bust and my butt, so I was happy to get beautiful pics while they are still there, lol. I already have some sag, so I know its only going to get worse, it's evident. I will have to figure out how to love the new me when I get there. I'm very happy that my health is improving so much, like you said, its a very small sacrifice :).
