Sometimes PTSD doesn't happen as a result of a physical trauma on oneself, it can happen to those who were around at the time of the traumatic event.
For example, I suffer from PTSD as a result of multiple tragic and traumatic events:
March 2010 I took my 21 year old son to the ER for strange and erratic behavior, he kept banging his head into the walls of our home (personally I thought he was on drugs). A few of my other children had come to sit with us while waiting for the lab results to come back before admitting him into inpatient counseling. As a precaution the ER doctor performed a CT scan to make sure he had not suffered a concussion from all the head banging. Within 10 minutes of the CT scan the room filled with nurses, doctors and a social worker----the CT scan illuminated a peach size tumor in his right frontal lobe, which turned out to be a Glioglastoma.
I remember every single detail even the thoughts I had when several nurses came in with the doctors and social worker....I thought....'this is not going to be good news" before a single word was even spoken. I remember listening to the doctors, the explanations, the fact he would not be going to an inpatient center, that this was the reason for his strange, erratic and violent behavior. Of course my triggers are ER's....not hospitals in general...but the ER specifically.
My husband (who is afflicted with Huntingons Disease) attempted suicide several months after our sons first brain surgery (who by the way was also diagnosed with Huntingtons Disease). We had been arguing throughout the day and into the evening. I left the home for a short time to take our granddaughter to her mother....when I returned my husband was in bed with the covers over his head. Thinking he was just trying to ignore me, so I ignored him back. After taking my shower, I crawled into bed and noticed that he was really serious about the ignoring me thing....it didn't take but just a few minutes for me to realize that he in fact was not ignoring me after all. At this point I didn't realize he had attempted suicide.
I met EMS at the hospital where my children were already present....the doctor took me aside and asked what had happened I explained about the arguing through out the day, having to leave the house and coming back and finding him in this comatose state, the doctor asked for a list of medications that he takes for his HD.....I still didn't know at this time that he attempted suicide. When I walked back into the hallway...one of the girls stood up and asked 'what did you do to daddy?' I was already wounded from my sons cancer, panicked from my husbands suicide attempt but then to add injury to injury was my children's accusations.
Husband spent five days in ICU before becoming coherent....My children and I took turns staying in the room with him. On the night my son stayed with dad, he decided to take pictures of my husbands body....bruises, pinch marks, etc., (injuries caused by EMS while performed CPR, lifting and transporting) to talk to an incoherent man who kept mumbling 'your mother is so mad' and decided to call adult CPS on me to accuse me of trying to kill their dad. Third traumatic event....
I am not the same person I was before these three traumatic events....I panic when my husband and/or son are out of the room for a certain length of time. I disassociated from friendships and relationships. I stopped being the kind of mother who cared anymore...I didn't (still don't want to but I do) want to babysit my grandchildren any more (some out of fear that if something happened to the babies who I be blamed?) While I raised 6 children (3 boys and 3 girls) a trip to the ER meant stitches and casts, but now I panic at the thought of anyone going to the ER. I have panic attacks almost daily sometimes several in a day.
My children and I reconciled though they never did apologize for their accusations and calling adult CPR...only saying they felt it was their duty. But I do not have the maternal feelings I once felt for them. My husband now has home health to care for his physical and medical needs which leaves us room to friendship instead of caregiver/patient relationship. My son, after two surgeries, radiation and 2 years of chemo is in a phase of remission.
You would think -- so everything worked out in the end -- but I still suffer from the trauma while everyone else seems to have moved on.
