Not all groups need facilitation toward a goal. Some groups need to be a safe space for a time — and that is enough.
Support groups easily fall into the trap of drama, with everyone giving advice and rescuing each other. It becomes a "just do this, read this, think this" conversation.
That is unhelpful.
What is, is to hear others' stories and tell your own stories in return: The facilitation becomes gently asking that no one answers anyone directly, no one suggests anything.
When you hear a story, that moves you, find a story in you that is true: And tell that.
That is helpful.
