Spongey Steering <Did Search> Clueless

Ok guys here is what i got. Last snow storm here in virginia i hit some black ice and spun out but drifted side ways for like 50 feet.
From that point on my steering feels extremely soft and when parking into a parking space i have to turn the wheel a bit more then normal… i feel like a tractor trailer driver somtimes. When i take a right turn for example the car feels liek it looses itself into the turn then pops back into working correctly as i turn the steering wheel to the left, Like an “S” manuver! I have herd everything from Tie rods to ball joints and somthin about latina women. None the less what would you guys think it could possably be and is it a do it yourselfer?
