I know how you are feeling!! When ever I talk to my relatives on the phone I get " How is your weight?" Not " How are you." Like my weight is a separate entity. It makes me feel so depressed. Good for you doing the extra flights of stairs!!! You were able to turn the negative into a positive and that is awesome. I am an emotional eater, so I would have wanted to turn immediately to food for comfort. Please don't let your dad upset you. He probably doesn't realize how much his words are hurting you. You are doing fantastic!! Keep up the good work. We are all here for you.
