This mental illness has increasingly appeared in medical reports in recent years. Like other mental disorders, they are difficult to understand, very difficult to treat and, unfortunately, can be impossible.
This is an escape from your past. In the past, when the patient had some very traumatic experiences, and now he wants to get rid of these memories. In every possible way. How can he do that? Well, very simple. They create a new identity.

The latter usually consists of completely opposite personality traits, so that the new character does not resemble the old character as much as possible. A person who has had an unpleasant experience. For women, it is often abuse and rape at an early age, and for men it is often infidelity, due to a car accident, and the death of a loved one. This disorder often develops for several years, and this is due to the fact that it has been attached to a person since childhood.
The patient tries to find comfort in self-harm in the form of cutting himself or falling to the uncontrolled ground, for example, beating, biting, kicking or other signs of aggression directed at a person. They hate themselves, they hide their bodies, because it can not change. They voluntarily undergo tattoos, piercings, liposuction and plastic surgery to give the body a slightly different look and not remind of traumatic experiences.
What is interesting is that the disease strengthens the need for improvement, awakens the tendency of perfectionists and forces them to set higher goals.

It is no exception that they become doctors and university teachers.
Personality changes are sudden, rapid and sudden, so they are rarely noticed by others. The result can come to the surface even for several decades, and only then the disorder will begin to heal. The longer the patient gets used to his new self, the more difficult it will be to treat, of course. They refuse to accept that the person they have been pretending to be for years does not really exist. They are so afraid of their old identity that they do not even have the courage to treat them.
