Your Phalaenopsis orchid is suffering from a lack of enough water. In your second image, that gray colored green tipped thing is a root. The material that is inside the pot that the roots are growing in is called the media.
In today's market, Phalaenopsis are often sold in sphagnum moss which is very easy and cheap to use as media. But it is very tricky to grow an orchid in long term. Why? Because it has a tendency to break down causing the roots to die. What we see first are limp leaves that are shriveling due to a lack of water to keep them plump.
I see your Phalaenopsis is now in bark and you have a new root there.
Phalaenopsis like NO sun, just a bright window. Temperatures from 65-85 degrees and to never go completely dry between waterings. How often do you water? You should be watering it well so the water really runs out the drainage holes. You should water every three or four days. Ice cubes are not a good idea!
Please look through our Orchid Forums where we have lots of stickies and threads about Phalaenopsis care!!! One such sticky is Growing Supermarket Orchids-Phalaenopsis.
But if you read through these you will gain a good deal of useful information.
