Thank the Lord that you are OK.. Ironically the same thing happened to me when I was in high school. A guy rear ended me @ 55 mph while I was in my Dad's , which he still has, 68 Oldmobile convertible and I did not have my seatbelt on. Luckily GM made cars like that then because no one in my car was scratched. The guy tried to get away, but the Cops get em.
I did not want to go to the Doctor, but people kept on telling me that there are people in accidents who are OK at the scene , but drop dead a week later due to a fractured skull, organ, whatever, so please GO TO THE HOSPITAL AND POST BACK HERE WHAT THEY HAVE COME UP WITH.
GOD BLESS .
