yes I would be, most likely you let it dry out too long between waterings and this probably killed the plant. Although wait it out a while and see if new growth sprouts from the crown. They're are usually always three leaves on the phalaenopsis, as one of the oldest die a new on appears to replace it.

If a phal has lost all its leaves, it's probably gone. Phals can get "crown rot", where all the leaves fall off overnight, and the plant is history.

However, if the new piece looks like a baby plant, with leaves and roots, that should live just fine. If the baby plant is on the end of the flower stalk, you can cut it off and pot it up; if it's at the base, just carefully remove the dead parts.
