I didn't really take any "before" shots either but I have a few photos that I keep in a hidden folder. They are the photos that when I saw myself in them I wanted to cry. I knew I had gained weight, but until I saw those photos I had no idea how fat I really was
So don't worry, I think a lot of us were reluctant to take "before" photos.
Congrats on the 18lbs that is no small feat!
