What should you do if you total out your own CAR ?

My friend totaled out her 2004 INFINITY G35 last night by mistakenly hitting a side wall. Both airbags deployed, and the windshield cracked but she still managed to drive it home and go to the hospital from there. She called me a few moments ago and said it was totaled out and should she call her insurance company (SAFE AUTO) or if not what should she do. Anyone have any suggestions or as to what the insurance company will do for her ?
