Climb into the passenger side, drive the car to your nearest fire department and ask them if they would use the "JAWS" to pop open your door. I have done this numberous times and it has always worked for me. Your car may look like crap after it's done, but normally the ones I have done look like crap before I start.
All joking aside, it sounds as though your outside door handle has come apart on the inside. You will need to remove the inside door panel to access it. This will be difficult with the door closed, so you might want to have a locksmith open it for you, or use a "Slim Jim tool" to get the door open.
Wishing everyone a safe and happy new year.
