Is it normal

Patient: I was in a bad car accident on Nov 30th of last year. Well, I was injured badly. I had a skull fracture, facial laceration, concusion, and a tibia plateau fracture of the right leg. Well, this flipped my life over. I’m still recovering. I think about the wreck all the time, I have times when I don’t want to be with anyone, I have reoccuring nightmares about it, I feel panicked when I get into a vehicle right now and I would just rather stay in my house. I don’t feel like myself at all. My question is, is this normal???? Is there something wrong with me??? I haven’t discussed it with my family or my family physician at this time.
