When my GP sends me to a specialist in physical health, she leaves out the mentally ill part of the story, and my medication. She recommends I do not tell them, or only in the last moment. Because we both know, if I signal a physical problem, and they know I have a history in MI, or the see the haldol…most docs here switch off their listening skills…and think nothing I say is true. I think this is one of the important factors. There’s more. But this is one.
A doctor’s assistent once spoke about accidently hurting a patient. She said blood was going everywhere. “But it doesn’t matter, because she was schizophrenic”. 
That’s absolutely awful. You all know of my experience re the falls I had, so I won’t go into full details. What will say is that I’d never have been treated that way, if I wasn’t an autistic and schizophrenic person.
