I didn't get a feeling of trashing the OP, but that's just me. As far as two spirit goes, depends on how you define it. Is it a situation where the personalities are so different and pronounced that they are conflicting with one another, or causing harm to personal relationships, work situation ect.? Or is it more of a flavor of expression of one's self, induced by certain activities, much like allowing music or film to put you in the mood?
If you are talking about serious issues like schizophrenia, bipolar disorder, depression, or cognative dissonance, well then suggesting a therapist is probably a good idea. If your talking about two souls cohabitating one body, maybe they need an exorcist!
