I wanted to shed a little light on this symptom that destroyed my life for 6 years, before finally overcoming it. Personally I don't think that Depersonalization Disorder exists and believe that this is just another symptom of anxiety that can in time be overcome. Depersonalization can be described as a recurring feeling of detachment from ones own body, as if being in a dream like state and not really ever in touch with reality. Many people complain of a fogy or hazy view of the world through their own eyes with depersonalization, and this symptom can not exist without anxiety. Depersonalization is caused by a mental shift in the part of the brain that is linked to the amygdala, which is the main organ responsible for anxiety. Cannabis, hallucinogens, antidepressants, caffeine and nicotine can all produce feelings resembling depersonalization, especially when taken in excess, It can also result from alcohol or benzodiazepine withdrawal.
Recovery comes by losing interest in your fear of the world and by trying to force recovery instead of accepting, understanding how you are adding to your depersonalization feelings, and letting time pass as you slowly let go of your tight grip on it which adds to the tension in your mind and body. Letting go of what you think peoples judgements of you are, will also take a lot of the pressures of trying to please people off of your shoulders, this will then translate into a big self esteem boost!
