car crash

This morning I had my very first car crash
. Im glad to say it wasn't my fault. The guy behind wasn't paying attention to the traffic jam ahead and drove straight into the back of me at about 50mph. He swerved at the last minute and caught the back right side of my car, sending it into a terrifying spin. It was a miracle I didn't hit another car. I can't believe how scary it was.
I hit my head on the side of the window, and I've got whiplash, but I don't think it's really bad. What I don't understand is the fact that this happened at about 7am this morning, and I'm still crying and shaking now (although not quite as bad) and it's 6.30pm. I keep telling myself to pull myself together, but I can't
I got back from the hospital about 2ish, took some tranquilisers that I'd been given and had a nap but the whole time I kept re-living the accident. Even though I'm ok, I feel like an emotional wreck.
I'm sure plenty of people on here have probably been in car crashes, so I was wondering whether this reaction is normal? The doctor told me I was in shock, but I expected it would go within an hour or two. I'm really surprised I still feel like this. Maybe I should have a nice hot drink and go back to sleep???????????
