Sorry to hear about this. I hate car smashes, I have had a couple and they really shake you up.
I'm not too sure if everybody will agree, but in my opinion, any repair could never bring the car back to its original condition. I had this happen once, and I was quite relieved to hear it was totalled by the insurance company.
I hope you are feeling healthy, and good luck with the insurance company.
