I would say that depends on whether you A) suspect you might have something diagnosable, dissociative identity disorder for example, or B) are more interested in exploring non-clinical models of plurality, i.e. modes of being more than one person occupying the same body which *don’t* necessarily meet diagnostic criteria (or which you think of more as an identity configuration rather than a disorder)
regarding plurality, like aside from the symptoms of a complex dissociative disorder, there are online communities for people who identify as plural regardless of their diagnosis. but online communities for multiplicity, disordered or otherwise, are TOOXIC as hell. depends what your priority is. but know that you aren’t alone.
