I had a colleague come up to me during my coffee break and hovering over my head saying "can I ask you a question?" and I instantly knew what he was going to say, and he goes "are you okay? You look really thin and frail these days" he is a sweetheart and he is someone I have worked with a long time ago and have great rapport with, so I just smiled and told him yes I am okay and thanked him for his concern.
Not a day goes by that I don't receive comments from multiple people on my physical appearance. How thin I look, how awesome I look ...etc. and it's just a multitude of opinions varying from you look awesome to are you sure you're not terminally ill? I asked my husband the other day if he thinks I look like death and he goes you look like a sports illustrated model, which at the end of the day, is the only opinion I value besides my own opinion of myself. People see it as drastic weight loss, I see it as one of the greatest successes of my life, using a tool that helped me lose weight and running with it resulting in great satisfaction and a much healthier body image.
I don't take these comments to heart, I look and feel great, and often think that most of these comments aren't personal, they are probably the byproduct of shock. Yes a fraction of them are ill-intended but then again, why should they matter to me? The good and bad, they're just opinions and they belong to others, not me.
