There's no way this isn't a pretty bad situation for you. Whether or not it closer to "real bummer" than "total catastrophe" is up in the air. How badly damaged is the car? You used "T-boned" and "sideswiped" in the description, and they're very different things. T-bone Usually means total loss, while sideswipe is frequently just some minor body damage. I hate to put it this way, but if the car could get away with $2-3k worth of body repair and paint, that's likely to be a pretty good outcome for you. If the car's a puddle of molten Ford somewhere then there's going to need to be a, well, creative solution to minimizing your loss and you should spend your first month's payment on some legal advice.
Real sorry this went down. Gotta be a huge bummer. And something I'll throw out there, though not particularly a bright side, is that even if you had comprehensive insurance you'd still be in a pretty big hole with the finance company if it's majorly damaged, as most people don't get gap coverage. The dealer wants all of his car money plus fees and finance charges, and the folks at Allstate were only gonna give you a settlement based on the depreciated value, which if you were lucky would be 90%.
