2006 Chevrolet Trailblazer steering problems

I was involved in an automobile accident out of state. I was traveling during the evening hours to try to avoid heavy traffic. I started having trouble with the dim lights and could only proceed using the bright lights. The next thing I realize is that I am unable to control the vehicle and struck another vehicle on the road. I then proceeded to slide down an embankment approximately 30 feet. My vehicle sustained enormous damage to the front and side of the vehicle.
