I'm so sorry... I'm sure that hurt. She is SO wrong! I had the surgery and if I don't exercise, I don't see the scale move at all. It literally WON'T move if I don't. I hope she isn't considering this surgery if that's how she truly feels because it would be a huge waste of her time and money.
I hope you are ok. Unfortunately, we are all warned of this kind of reaction from people. Remember, you are stronger than you think! Maybe she will figure it out someday, maybe not, but right now you can't afford the negativity. If you need a woman to vent to, feel free I inbox me anytime. you're doing fabulous! Keep your chin up!!!
