I think it could be that the rejection of the psychiatrist (who sounds like not a good fit for you) has perhaps clouded reality. The psychiatrist, if I understood the other thread, had only met you one time prior to the time where he said you all did not match up. And he was not giving you what you wanted (the meds) even though I see it may feel like personal rejection . I think it could be possible that you are painting with too broad a brush here.
Have you had a chance to talk to therapist about the psychiatrist situation?
