Sara, a life-long ballet student, says she feels like she does not want to participate in ballet anymore. she also states she is tired and cannot seem to get enough sleep. which disorder is sara most likely experiencing? (1 point)

I believe the answer is: generalized anxiety disorder 

generalized anxiety disorder is a constant worrying that caused by different aspects of one's life.
Even though generalized anxiety disorder  would be hard to spot, it could be characterized by loss interest in hobby, detachment from social life, or lack of sleep
