2006 Chevrolet Equinox suspension problems

I ran off the side of the road into a guardrail and could not stop until I was on top of the guardrail into an embankment. My entire front end was destroyed as well as most of the underneath of the car. My face hit the steering wheel causing me to lose consciousness as well as giving me a black eye, crooked teeth, cuts, broken dental appliances, and my teeth went through my lip.

I am not exactly sure what it is that's wrong with my car it has to do with my brakes and the pedal.. I thought the brake pads were bad. When I changed them it had almost brand new ones on.. My traction control light stays on and my ABS light stays on.. The pedal has hard spots in it and it just grinds like the pads are bad when I hit my brakes! Its not safe and I don't know what's wrong with it! My research shows I'm not the only one with this car that has the problem. Its been a problem for a bit now..
