It depends on the stakes and level of trauma of the situation regarding how much I will ruminate. It is about self protection when in trauma. Sometimes, it’s to repeat something pleasurable to replay a conversation or comment that was nice or funny. I agree it can become emotionally exhausting and take a toll on your health. I can let go and just experience plenty of things that are of little significance and consequence. It’s the very important or traumatic situations that are impossible for me to not dwell and my mind work overtime.
