I work in an EBD school where I dealt with a serious incident involving scissors and compasses, this happened about 6 weeks ago. The first week was horrendous, struggled to motivate myself and sleep was nearly non-existent. After then though things settled down but I still dont feel that I am sleeping right, I regularly have dreams but wouldn't describe them as nightmares. Sometimes it randomly pops into my brain through the day and it all starts again about what things I could of done differently, did I see it coming etc etc? We are now 6 weeks later, and in a maths lesson one of the students had scissors in his hands and was innocently cutting out things, but I went straight into fight or flight mode and left the classroom I could feel my heart pumping out my chest. I don't think I have any post traumatic stress but I believe its more cognitive and inside I still keep reflecting on the incident. Do you think its time to see the doctor? What I dont want to happen is this to turn into a ticking timebomb.
