I know how you feel! I've lost almost the same amount of weight as you (16 pounds) and my family has been very supportive and will say something every now and then. But last weekend I saw a friend I hadn't seen since Febuary and she stated, "You've lost weight!"
I squeed and said I had to hug her. She was a little surprised, but I explained she was the first person besides family to say something, and she understood.
It was a little awkward because my best friend was also standing right there, someone I also don't see very often. I hadn't said anything to her, and I didn't expect her to say anything back. She LITERALLY does not see weight. She was SHOCKED when I told her I had gained 50 pounds since high school. How do you not notice that? Ah, Tammy....
Still, let's give ourselves a little happy veggie dance, shall we?
