Hon, you are not alone. I experience similar events and dissociated reactions, especially around people like at our new job. It's seems to be dealing with other humans that throws us all off. Too many social cues and skills lacking, plus similar/like recall to traumas past and present.

We just experienced a situation at work where the other co-employees were harshly joking using us at a butt of their jokes which took me back to the earlier years of my abused life.. We just wanted to ask them to stop, but that triggered the Angry One which stood up and told them off- we were embarrased for days. Thank God it was right before the weekend. By Monday, we had resolved to keep our head down, do our job, and let it all blow over. Within a week we were all good again, and actually enjoyed being with the other employees.

Sometimes when we get triggered, theres a chance that we took it the wrong way, bouncing through the day. We live from one trigger to the next.

Please hang in there and cement yourself to a resolve in surviving the present situation. I hope it works out well for you.
