Do you experience unreality, detachment, or being an outside observer with respect to your thoughts, feelings, body, or actions (e.g., perceptual alterations, distorted sense of time)?
Do you experience of unreality or detachment with respect to surroundings (e.g., individuals or objects are experienced as unreal, foggy, lifeless, or visually distorted).
During the depersonalization or derealization experiences, does reality testing (i.e., your ability to see and understand a situation for what it really is) remain intact?
Do the symptoms cause significant distress or impairment in important areas of functioning (e.g., social, occupational)?
Can you confirm that the problem is not attributable to the effects of a substance (e.g., a drug of abuse, medication) or another medical condition (e.g., seizures).?
Can you confirm that the disturbance is not better explained by another mental disorder, such as schizophrenia, panic disorder, a major depressive disorder, acute stress disorder, posttraumatic stress disorder, or another dissociative disorder?
There is most likely no reason for you to be concerned, as the most important characteristics of depersonalization/derealization disorder are persistent or recurrent episodes when you feel like you're observing yourself from outside your body (depersonalization) or you feel like things around you aren't real (derealization), or both. These feelings can be very distressing, you may feel like you are living in a dream. Some people may experience feelings of depersonalization or derealization at some point in their lives, but when these feelings keep coming back and impair your daily functioning, it may be a good idea to seek out a doctor.
Based on your answers, it may be wise to seek medical attention to discuss your symptoms. If you have feelings of depersonalization or derealization that are distressing, recurrent and that interfere with daily activities, you should see your doctor as soon as possible. Besides asking you about your symptoms, thoughts, feelings and behaviors, the doctor may want to perform a physical exam and lab tests. If your doctor concludes that treatment is necessary, they will refer you to a psychologist.
Based on your answers, it is highly recommended that you seek medical help. Episodes of this disorder can be very disabling and can cause many other problems. You may have relationship issues or depression. You may also not function well at work or school and you may have a hard time remembering things. The most common treatment used for this disorder is psychotherapy and sometimes medication. Remember that this disorder is treatable, and staying in touch with supportive people, like family and friends can greatly ease your condition.
