Commenting on food choices ok?

Is that normal when you eat something you like and there is always that one person that goes 'omg how much are you eating it's already 7 in the morning. I still didn't eat anything' and I ate 3 small sandwiches (I'm a binge eater and that's a progress). I overate again today (1.8k calories, maintenance for today bc i worked out but for normal days it's a lot). She's a very close friend and we joke around together so i know she doesn't mean any harm with that comment but I still feel bad. Am I overreacting?
