I witnessed something terrible this evening at 5:00pm. I know it is still fresh since only 4.5 hours have passed, but I am having major problems getting it out of my head. I keep getting these flashes and having anxiety attacks.

My boyfriend is trying to help me, but he doesn't really know what to do. My animals are helping distract me, but I still keep seeing these images in my mind.

Does anyone know any technique or trick I can do to try to put my mind at ease?

By the way, it was a motorcycle accident I witnessed. I was first on the scene and so got deeply involved ... still shaking. I was actually really close behind the guy when it happened, but I glanced away for a second and then looked back to see his body in the street. I've never been in a situation like that before and there was a lot of blood. The man will be okay though I'm pretty sure.
