Just got off a cruise- still feel rocking and just extremely tired- been off cruise since 12/16 it's now 12/20. could it be anxiety related?

A combination: Of things - probably some motion sickness and perhaps jetlag if you took a cruise in another timezone. A medication called Antivert (meclizine) prescribed by a physician might be helpful with your symptoms.

May not be: Mal de debarquement, the “sickness of disembarkment, ” occurs when habituation to background rhythmic movement on a ship, becomes resistant to readaption to stable conditions once landed. It results in a perception of ongoing motion typically described as rocking, bobbing, or swaying. In most cases this goes away in a few hours/days, but sometimes can persist for weeks/months. See your doctor.
