I fit this the best. Unfortunately this is the UK's breakdown. Not in the United States where I am.:
OSDD-1b might experience their alters more as different versions of themselves, though they're more likely to experience a noticeable change in skills, memory, temperament, or overall personality. It is important to note that even the least differentiated OSDD-1b parts are still more differentiated, separate, and autonomous than the most developed parts that can be present in borderline personality disorder, posttraumatic stress disorder, or complex posttraumatic stress disorder, none of which involve dissociated parts that have a unique sense of self or self history. Even OSDD-1a parts are often more differentiated than the pure dissociated trauma materials, emotions, or attachment needs present in these latter disorders. As well, some individuals with OSDD-1b do have highly distinct alters such as those often found in DID. For these individuals, the main defining factor is their lack of inter-identity amnesia.
