Naming a problem can help. Repeating it without considering a next step can keep it occupying all your attention.
Sometimes we need to say that something is wrong. We need to be heard, seek support, or ask for change. That is different from returning to the same complaint so often that it becomes our most practiced conversation. I think the useful question is what we need next. Understanding? A decision? A boundary? A different approach? Give the problem an honest name, then consider what would help.
