I think it starts with accepting ones own condition. If one is anxious about one's condition, I doubt there is much chance at enduring others negative comments. One needs to be secure in oneself first. Being educated about ones symptoms and how to moderate them helps.
If there is any chance at getting the others to watch the YouTube "You Look Great" video series, it should help them.
