The most important thing is your safety. If you do not feel the car is safe to drive then please do not. Your insurance may offer one free towing.
The belt that drives the power steering also drives the AC. So unless you were running the AC this time of year or turned it on that would be an indication. The best way is to look. I attached a picture of the belt and the water pump is number two and six depending on if you have AC.
If there is no leak then it may not be a blown hose. Another possibility with the miles you have is internal failure of the rack-n-pinion. I attached a picture showing it is number six.
I hope that helps, without a visual I am only guessing. I also do not want to be doom and gloom, but those are the possibilities based on what you have said.
