Made the mistake of being fat in public

Had my girls' pediatric appointment today. We just recently moved so it was their first visit with their new doctor. The girls were being hectic and by the end, all of my youngest's puffs had ended up on the floor (which my oldest and I picked up and threw away because we're not animals), but their doctor seemed really nice. As my husband left to get their social security info from the car to finish up the paper work, she starts asking me about my youngest milestones and what words she was saying, etc. When she randomly asked me if I heard of noom. I say no thinking it's something for toddlers since we were discussing my toddler. But no, it was a weightloss app. I get she was being nice.... but it hurts when you have an appointment about your kids, but somehow your weight ends up getting brought up. I've lost 50 pounds so far. A weightloss journey she couldn't possibly know just meeting me. 50 pounds, but I'm still reminded that until I lose all of it my weight will always be up for discussion. Maybe I'm being overly emotional because I'm on my period so my mood isn't the greatest, and I feel like shit from being so bloated. But it would be nice if people didn't assume I had no control over myself. It would be nice if people stayed on topic unless asked.
