Annie... if I were to be in a car accident I would guess probably definitely call my therapist that is why I initially went there for to get over the fear of driving after almost being killed in a car accident. Through EMDR I also realize that it caused additional distress because of my need to not rely on other people after the accident. I don't like asking for help or relying on other people I don't trust other people and it causes me to dissociate. So I guess it just depends on the situation but for me a car accident would be a huge trigger and reason to call my therapist and he would totally understand why. I also guess it depends on the seriousness of the accident. In my case I broke my neck amongst other things so it was pretty serious.
