I am so sorry for what that woman said! Some people have simply removed the filter from their brain.
I know how hard it is to not let something like this bother you. Once, a few years back, I was at dinner with my whole family (there was about 15 of us), and my young brother, he was about 4 at the time, said very loudly, Sissy, you are fat! And of course it happened when things were quiet so everyone heard. I wanted to crawl into a hole and never come out. I knew I was too big, and I knew everyone else knew (obviously) but when its pointed out like that, it just hurts so much!
Take what that woman said and use it as motivation! Just keeping telling yourself, you know what lady, Ill show you!
But in the end, focus on yourself and forget everyone else! This journey is about you, and you alone. You have made a great choice to start this journey again.
Ill never understand people who can be so mean like that. I don't care how bad of a day someone is having, or anything bad going on in their life, it is NO excuse for being rude and hurting other people's feelings.
So, keep going girl! You can do this!! And forget the nasty naysayers!!!
