Help! Ficus Audrey wilting after sun over-exposure

I have been a bad plant parent and left my poor ficus in a hot sunny car for a few hours during a move. I've now gotten it to a place where it gets the right amount of sun (I think) and watered it, but it still isn't doing well. First one, now two leaves are drooping, and the top of the stem is shriveled. What can I do to help it?
