Oh my word! You are lucky to be alive. That's not rear ended that's
a total car wreck! What the heck hit you, a train

I am sorry your head hurts but hun your really one lucky lady that
you came out of that wreck alive and walking.
That's unbelievable to have that kind of damage from behind unless
he was going 90 and not looking.
Hope you feel better soon and have no after effects from this.
