I remember learning about conversion disorder (hysteria) in school. I didn't know it was linked to anxiety and bipolar, though.

I think the only thing I have is that when I'm having an episode my pain tolerance goes way, way up. Also, even if I was starving right before it starts, I suddenly can't eat. Food just becomes disgusting and I don't want to eat. It doesn't go away until several hours after the episode, sometimes I'll wake up starving. I don't think I have conversion disorder, though, and I don't think that's what is causing my difficulties with speach, because those problems come on for no reason, even when I'm calm and and at rest.
