Post Traumatic Stress Disorder after car accident?

I just got into a car accident today i was turning left on a street where the light was green as it was for the cars coming straight but there was only one coming a white four door pathfinder it was a technician with extra stuff in the back i remember he was a good 8 seconds coming from other direction and im turning next thing i know he comes out of nowhere his front bumper hits my penger side and i spin 2 times got sideswiped and next thing i know i am in a state of shock my whole penger side was mushed up and the transmission was jammed and the chasey was bent but luckily i only suffered some bruises on my ribs from the seatbelt on impact had i not been wearing it only god knows what would happen but nobody was seriously hurt and the state trooper came out with the theory that i was the one at fault im 22 and this is my first accident and i got a 145 dollar ticket on top of that i have to attend traffic school too along with the fine so i dont get 3 points off my license.. so after that my parents took me to the emergency room and the doctor said that im hurting on my right rib is cause on impact the seatbelt moved some and thats what caused it but in the end my parents said all that matters is that you are okay and did not suffer any serious injuries i was wearing a jesus pendant with my chain so i thank god i was not seriously injured and did not have to end up going to the hospital in an ambulance i learned my lesson and will take extreme caution when i drive again .... is it normal to feel this way after a car accident? ps jesus is good and i pray that he can help me get through this
