Is my gtr totaled?

Yes, it is.

Pretty sure any impact hard enough to break the pole would cause a good amount of damage. Did the airbags go off? As soon as they add up all the front pieces with both intercoolers, radiator, core support, both fenders, hood, bumper cover, headlights and more plus all assciated labor and paint work, it's a total loss. Buy it back cheap and fix it and pocket leftover insurance money.
