Cover art for The Wreckage lyrics by Vanessa Carlton

It doesn't sound like suicide to me, but it does sound like a car crash. Like maybe she was in a car crash and the people she was in the car with got hurt more seriously than her or died and it could have been just as easy for her to die, and now she feels bad because it could have been her instead of them. But I agree with the thing about death happening any time. That makes sense.
