She sounds kind of like my sister-in-law who sticks you with sarcastic barbs every other sentence. Why do some people have to put other people down to feel superior? It's just sad. But it is THEIR problem, not yours. Rise above and know that you are a good person and a good mother and don't let the petty people bring you down to their level. It's really difficult to put things like this out of your mind when you are a good person because you don't understand cruel people. Been there done that! The harsh words repeat over and over in your brain and it's hard to get them out. But don't second guess yourself, just do what you know is right. Ok, end of sermon.
