Lisa, I have to agree with Hetty ... it looks like your poor Orchid might be a goner.
I notice it's planted in what appears to be spaghnum moss, which either stays soggy and does not allow much air circulation around the plants roots, causing them to rot .... or it gets as hard as a rock, causing the same issues. Although many folks grow
Moth Orchid (Phalaenopsis) in containers, the wood baskets with orchid bark chips would probably be a much better choice for potting medium because it would drain quickly and allow for air to reach the roots.
