Many steps forward, a gazillion back.
Those people who make fun of others have no self esteem themselves and are trying to make themselves feel better. I don't take that from anyone any more. I look them straight in the eye and say that they are being rude and it's a good thing their mother isn't there to hear what they've become. That usually takes the wind out of their sails!! You've done well and being able to walk around is awesome. I still use a walker, so being able to walk without assistance will be wonderful. Just remember all of the positives that have happened so far and forget about the jerks!!
don't let stupid people who have no idea about weight-loss get you down. It sounds like you have come very far in your weight-loss journey. Your activity level has increased and that is a major part of weight loss.
Continue to do what you doing. The weight will come off and you will feel much better about yourself about life.
good luck as you continue your weight-loss journey.
