Having been a member of musical/operatic groups since my teens, you have my sympathy as over the years I’ve had so many situations when I feel my good nature was tested. An incompetent bully took over a group I loved and cutting the story short, I left, leaving behind good friends I had known for many years. I ruminated and mourned it like a bereavement.
I also asked myself why no one had taken my side, but the truth is people want to hang on naturally to what they have and not side with a rebel, even if they see injustice. Self preservation and I understand that now.
I too joined another group but was amazed to hear recently that “Miss Mountshaft” and her cohort had gone! I’ve returned to the sadly depleted company and am so pleased to see my friends again as it was the social side too I enjoyed.
So you never know, things change. Chin up and as Noel Coward said “Rise above it darling” or something to that effect.
