A little morning sun won't hurt it!
A great thing about Phalaenopsis is that they respond well when repotted! Once yours is in the proper mix, within 4-6 weeks, you will see new root development. With new roots the leaves will hydrate and get firmer. New leaf production will start. But you must repot as soon as you can. The longer you delay, the longer the recovery will take but I am confident that the plant will look a whole lot better a year from now and it will bloom quite probably after the new year. Good luck and please keep us updated.
Just don't use too big of a pot!
