Congratulations, Sheila! I remember that moment SO vividly -- I'll even bore you to tears and tell you about it.
Even though every wall of my gym is covered in mirrors, I refused to look at myself below my neck when I first started working out. I'd stare at my face but wouldn't acknowledge the rest of me (it's the whole denial thing; how I was able to pretend that I wasn't fat for the longest time

).
One day I was working out with my trainer, doing BB curls. I was facing a mirror and looking fixedly at my face, not my arms. At that point, I been working out for about seven months and had lost about 75 pounds -- but didn't feel like I looked very different at all.
My trainer grabbed me and said -- look, look, watch your muscles working, they're beautiful. And he made me watch my biceps while I was doing curls and I couldn't believe it! I could see the muscles working and it was the most amazing thing -- I almost cried. It was the first time that I could see muscles coming out from under all that fat.
It's definitely the best feeling in the world!
