Book excerpt: As a neuroscientist who has successfully completely overcome chronic depersonalization and derealization (DPDR), I am driven to teach every last sufferer a). what this 'disorder' really is and b). how to cure it in a matter of days and ensure that you never relapse.Regardless of how dissociated and lost you currently feel, you are as real, safe and alive as you were when you were a curious child. What's more, I am going to teach you how to make these feelings vanish. There is nothing intractable about dissociative anxiety; when you are ready to launch yourself towards recovery and fight against the illusion, it disappears - it simply can no longer be sustained when you are truly committed to living in the real world.
