Guessing the brake pad wore through to the backing plate, started scraping pretty good, drove for 3 more days like that, then the caliper eventually puked out the backing plate which dramatically changed pedal feel. I'll even take it a step further, it was the inboard pad backing plate.
OP, don't drive your car at all until this is fixed. Not even to a shop, have it towed.
