1997 ford taurus steering problems

i think i may have oversteered my taurus. a couple of nights ago i was making a u-turn and as i pulled out of it, right was left and left was right. did i reverse the hydraulics or something by turning too hard? i heard it strain but nothing sounded broken. it is very dangerous taking the kids to school and trying to avoid crossing children in the school cross-walks. anybody have any ideas? i want to do the work myself to save money and i bought a tool set from Walgreen's so i think i am set on tools. will take any help.
