Oh Marcy that is terrible. It was only an accident, don't beat yourself up too much about it. It was not your weight, the same thing could have happened with your 6 year old stepping on it.
You are absolutely right about this being a different weight loss journey than you've experienced before. Just remember it took years to put it on...losing it slowly will help to adjust our behaviors and help us deal with the root of the problem. Hang in there.
So sorry about Pandie.
