Hi Depersonalization/derealization disorder is a mental health condition that can cause a person to experience either a persistent or recurring feeling of being outside of their body (depersonalization) or a sense that what s happening around them isn t real (derealization) or both. Some people who are dealing with depersonalization experience alexithymia—an inability to recognize or describe emotions. There also are potential physical symptom, the sense that your body and limbs are distorted,swollen or shrunken. You may feel physically numb to sensations. Severe stress, anxiety, and depression are common triggers. Often, people experienced past trauma in their lives. The most effective way to deal with depersonalization/derealization disorder is with psychotherapy. There are many types of therapy and techniques for treating psychiatric disorders such as cognitive-behavioral therapy, which combines strategies for blocking obsessive thinking about feeling things aren t real and distraction techniques.
