So your not sick?

I have been very proud of my postpartum weight loss and excited to be back to where I want to be. Until today when a co worker asked me about my weight. The conversation started well enough with him asking if I had gone below my pre-pregnancy weight. Of course the obvious conversation followed. I admitted that I hadn't been trying hard to loose the weight and exercising when I can though less than before. He asked how I managed to loose the weight considering what I had just told him. So I told him it was probably the nursing that helped out a lot. to which he responded "Oh good so your not sick then!"

as much as I appreciate the fact that he is happy that I am healthy I'm a little worried that he thought I looked sick now...
