Although family history can be relevant, I find it ludicrous that she is basing her medication recomendation upon what disease your mother had. I'm glad you're having your previous records sent, and will be seeing someone new. Schizoprenia and dissociative disorders do have overlapping symptoms, and can be difficult to diagnose. I hope your next provider really really listens to you, and will be able to understand you, and therefore help you more effectively.
