Adding antifreeze to water in your radiator will not make it run hot, unless you are have a very high portion of antifreeze to water. Antifreeze/coolant raises the boiling point of water to keep it from boiling out and lowers the freezing point to keep it from freezing up.

If it is full of water now and there is no room for antifreeze. Then drain the radiator and refill with the correct mixture of antifreeze and water. This should not only help your cooling issue but also will prevent it from freezing up.

As to the current state of your car, if it is parked near a building or somewhere that might prevent it from being as cold, you might be ok. In any case start it and don't drive anywhere until it has proven that it can maintain a solid temperature.

To be clear, what's in the radiator now is toxic (water + some antifreeze). You can't just pour it down the drain. –  Bob Cross Nov 12 '13 at 20:04
    
Yes, follow local guidelines when disposing of any fluids. @Bob, many places in the south actually do allow anitfreeze down the drain as long as it is flushed with extra water. –  jzd Nov 12 '13 at 20:51
    
Thanks. I was just saving to be able to get it to repair shop but it got to freezing outside and didn't want to even start if not safe. Thanks again! –  user3952 Nov 13 '13 at 11:03
