Anything that is ‘high energy’ can feel like too much to a compromised nervous system, even emotions we perceive as positive. Though it is important to note, there is no such thing as a negative emotion. The Sympathetic Nervous System is ON when it comes to both excitement and threat, and if we have unresolved trauma, particularly early/developmental trauma, it can be very difficult for the system to distinguish between these things — it all just feels like too much.
