You did some great self care there!
Actually, if that was a coda group by anychance, quite a few people have that experience. We have made jokes about coda,

not sure what the rules are here about being sarcastic, I feel the same as you, I have oftne felt that, I have left meetings in tears, its not you. It just shoulnd be like that. You would probably be more caring to a newcomer on thier own.
well done for sharing what happened, and getting help.
