Remember that her reaction was more about her than it was about you. Remember that while she went off on you because of her own issues, other members were quite supportive and helpful.

That's the stuff of life. Realizing that it isn't all completely black and white, people come in varieties. People react more out of their own issues than out of really meaning to attack you. We don't have to own other people's issues.

The therapist stepped in and spoke to her about her behavior, and I suspect the other individual may have learned a bit herself in the process. One can hope anyway.
