First off you're amazing for losing that much weight already. I'm totally jealous.
Moving on to the dumb people that said such hurtful things... I think you did a great job by moving and not going down to their level. You are a great example for your daughter. We all have a days or even weeks where we give into the deliciousness of all the bad things that are bad for us. Now don't let those days dictate what you want to accomplish. Pick yourself up and move on in the same manner you did with those dumb people.
I hope you have a better rest of the week.
