Growing a Potted Hydrangea?

I am trying to save a hydrangea received as gift from a funeral. The hydrangea was sitting by a vent where air conditioning was blowing. When I picked it up from funeral home, the pink blooms were wilted as well as the leaves. However, the new leaves were not damaged. I watered it with room temperature water so I would not further damage the plant.

Some of the bigger leaves are so wilted they a brittle like a leaf that has fallen from a tree. What do I do with the brittle leaves and the blooms that have been damaged. I live in Kentucky and am keeping this inside until all threats of frost have passed. Thanks for your input.
