What you have described seems characteristic of depersonalization or derealization. Neither are symptoms of schizophrenia. Individuals who have experienced depersonalization describe feeling as though their body is unreal or that they are an external observer of their body. Other common phrases used to describe the experience of depersonalization, include “robot-like,” “puppet-like” or “acting a part.”
Derealization is the feeling of being detached from one’s environment. Both depersonalization and derealization are associated with high levels of stress, anxiety, a history of emotional, physical or sexual abuse and illicit drug use, particularly among those who have used or are currently using hallucinogenic drugs.
I am assuming this is the first time you have had such an experience. Individuals who have chronic episodes of depersonalization may have depersonalization disorder. Depersonalization disorder is part of a larger group of disorders known as dissociative disorders. Dissociative disorders are mental health disorders that are characterized by disruptions in memory, consciousness and perception. Depersonalization and derealization may also be symptoms of physical health disorders including epilepsy or other seizure disorders.
I am glad you are being evaluated by a mental health professional. You should also consult a medical professional to rule out a physical health problem. Try not to be alarmed. For many people, their symptoms simply disappear on their own. For those who continue to experience symptoms, psychotherapy is the main treatment approach. Medication may also help. There is no specific medication to treat dissociative disorders but anti-anxiety or antidepressant medications can provide some relief. I wish you the best. Please take care.
