Very very sorry to hear this mate.
Something very very similar happened to me as well with identical damage, even down to my left headlight breaking, but the right didn't. Only thing is my bonnet didn't go that high. Check the thread out here:

To repair this, you're gonna need:
Radiator Core Support
Upper Bumper bar
Centre Bumper bar
Bumper
Bonnet
Bonnet Hinges
Radiator
Tension Rod brackets
Left Headlight
A/C Rad will also be shot
Also the car is going to most probably need to be jigged a bit, the front the chassis rails are probably bent slightly.
The total cost bill was very high, so theres no doubt the insurance company will write it off
Let me know if you need any help mate!
