i have been on the other side of that before, my mother was hit by a car doing 100 on the free way crossing a pedestrian crossing, She was flown to hospital i remember all of this in great detail even tho i did not see here on the floor there it was still a shock and big impact. My little brother then 20ish found her on the road just moments after the hit as he heard the sounds and went running from home.

as for what drs will say talk to a specialist and if you show signs of withdrawal or depression go on anti depressants. I am happy to talk to you via pm if you want to ask me anything.
