Depersonalization is a temporary way your brain deals with high levels of stress. Temporary can mean a an hour, a day, a month or a year. However long it lasts, it is always temporary and never last a lifetime. In most cases the depersonalization goes away once the person starts treatment for the root cause of the stress. Remember, depersonalization is a symptom it is not the problem, just like a cough is a symptom of a cold, DP is a symptom of stress. A good thing to do is to learn about depersonalization by reading books, watching videos and speaking to professional who can shed some light on this debilitating disorder.
Once you have understood the root of your DP you can begin to heal, it is usually some form of trauma, you might have to dig deep. The problem is that many people become really afraid of their DP symptoms and that causes them to focus more on them which in turn makes the depersonalization even worse. It may be very difficult to focus on anything other than your DP but you must try to keep yourself busy with things that keep your mind off it, and understand that this is just a way that your mind/body is trying to cope with the trauma. Your brain is in a state of “shock.” This doesn’t mean you should ignore the symptoms, but the less you pay attention to them the faster they will go away. Once you accept the depersonalization and know that it is a result of trauma you can start your path to recovery.
