Dracaena plant wilting after fixing over-watering problem?

I noticed this morning that my dracaena was wilting. I looked up the characteristics it showed (wilting, yellow bottom leaves mainly) and the water was moist after days of not watering it. I suspected that it had been over watered so I took it outside and planned on digging it up but really it slid right out of the soil with a gentle pull. It had been standing in water for the last few days. I looked up what to do with an over watered plant and then followed the directions of letting the soil dry out and cleaning the soil out from the roots. I even checked the larger roots and trimmed what didn't fit the category of "healthy" roots. I checked the trunk and it still feels firm rather than a possibly-rotted hollow feel. I set it in the shade (but still 91F weather) for around 30-40 minutes and then decided that the soil dried enough for a re-pot. It's still moist but not soaking like it was. I put the wetter soil at the top and left it outside a little longer to dry out some more. I went outside to check on it and the leaves are all wilted now and the tops of the branches aren't standing upright any longer, they're hanging over to the sides and just look unhealthy. I brought it inside and closed my window in case it's gotten too much sun. What should I do?
