Honestly look 100 miles the other directions, possibly in the Native American or Buddhist communities, for a new therapist. Are you on any medication to need a psychiatrist? If you take out the cultural parts.
Do you get social anxiety? Is the way you speak (cadence) different then others? Do you get suspicious or paranoid of others? Do you have friends? Are your emotions different then others?
Ask how they ruled out depression, anxiety and psychosis? Ask for another psych exam from a Native American psychiatrist. Tell them you don't agree and you worry it's a culture "thing".
