I had a "best friend" like that. I lost 70 lbs on Atkins (I know y'all are groaning lol) and everyone was complimenting me EXCEPT her. She said she "just couldn't see it". Then one day she saw it & all she could say was " taking it off is easy (it was???) but MAINTAINING it is the hard part so BE PREPARED". Honey don't let them get them down. You are not doing this for them, you are doing this for YOU! Don't even waste your time on toxic energy. You just keep on putting out there your good energy and that's what you will attract. And as the mom of 2 kids that need speech, I WISH I had someone like you, esp someone that would come to my house!! Bless you for the work you do with the kids. . Stay strong & it's ok to vent.
