When we're threatened, we are not relational, we're hostile instead. The interaction becomes a zero-sum game where the importance is placed on gaining back control - sense of safety, agency and validation.
Agency and validation bring us a sense of safety and settles down the nervous system - we become calmer and curious. But when we are unaware that we're triggered and use words to fight over someone or something, we don't get to relate and regulate into safety.
When someone is triggered, know that you're not talking to that person, you're relating to that person's nervous system, and the things they say signal the level of activation.
I think that understanding the nervous system regulation is key to human relationships. When you know your triggers, you can give heads up to the people you're relating to. When you learn the cues about your person's dysregulation, you can address the matter later after the nervous system has been more regulated. Here are some cues for you.
As a resource, I'm using TherapyJeff's content that I liked and found useful for myself and also my clients to reflect on.
The next time you feel disconnected from someone who you want to feel connected to, and you hear yourself saying something like in these 12 examples, pause and pay attention to how you feel in your body, announce a break, and give yourself some time to feel and be with your own bodily experience. Have that conversation after some minutes or hours, or give it a day to cool off.
When you struggle to deal with your emotions and triggers, get support either from a trusted friend or a professional.
