Sorry to hear it. Glad you seem mostly OK. It's not clear in your description: Are you saying that the van left the road to avoid rear-ending the same stopped vehicle you hit? Keep in mind that locking the rear tire up shouldn't reduce the stopping distance for the front brake when upright and straight, though it obviously can cause an accident.
I'm worried about the passing out. Are you sure you didn't hit your head? Heal up quick.
If they prescribe more pain killers, be sure to start posting moar for our amusement.
