I came here to look for a post just like this. Ruminating is a defense, a response from one's nervous system to a perceived lack of safety. And mindfulness and therapies are very effective in treating the root cause of that nervous system response. Just a shout to say that there are some situations where cognitive-based therapy isn't the optimal answer, where more experiential forms of therapy like IFS or AEDP are far more effective. For example, people who grew up with caretakers who were not able to teach and model proper emotional regulation would likely respond better to experiential therapies vs. cognitive.
