Burnt phalaenopsis?? Yellow leaves and droopy

[paigee229]

Hi,
I'm new on this, but joined because I received a phalaenopsis just 3 days ago, and I think I've hurt it already! I left it on my desk near a skylight while I was gone for a (really sunny) day, and when I came back it looked terribly sick. I know now that I should have moved it, but is there a way to nurse it back to health? The lowest leaves are completely yellow and wrinkly, and the upper leaves have significant yellow spots on them. Two buds have fallen off, and the blooms are droopy and have a couple browns spots. The roots look almost the same except that some have a pinkish tinge on the ends. I have attached one before and several after pictures...thank you so much to anyone that knows more about orchids than me!
